by Sean McIntosh, OSG District Sales Manager OSG’s HY-PRO® CARB VGM end mill boosts productivity and lowers cost per part in aerospace bracket application. Founded in 1951 in Phoenix, Arizona, United States, Allied Tool & Die Co. is a family-owned precision machine and fabrication company that specializes in the manufacturing of quality parts for aerospace, medical, communications and commercial industries throughout the world. Seventy years since its establishment, this privately owned shop has grown with multiple facilities and an estimated 32,000 square feet of manufacturing space in Phoenix, Arizona. One of the challenges Allied Tool & Die faced recently was the machining of aerospace brackets made of Inconel 718. As is with most shops, machining Inconel 718 is time consuming. Moreover, due to the material’s special high strength and heat resistance properties, short tool life is a common obstacle. In search for performance improvement, Allied Tool & Die CNC Process and Machining Manager Jamie Lerma reached out to his local OSG representative for new solutions. Lerma had worked with OSG previously on a 13-8 stainless steel application by utilizing OSG’s HY-PRO® CARB VGM series end mill to achieve high-efficiency milling. OSG’s HY-PRO® CARB VGM is a high performance variable geometry end mill series. Its variable index and unique flute geometry enable the reduction of vibration and chatter, promoting smooth and stable cutting with low cutting forces. With the addition of OSG proprietary multi-layer EXO coating, higher wear and heat resistance is achieved to prolong tool life. OSG’s VGM offering features 5-, 6- and 7-flute lineups, and is available with multiple lengths of cut, with both square end and corner radius variations. This series is suitable for carbon steels, alloy steels, die steels, stainless steels, cast iron, nickel alloy, titanium, and hardened steels up to 45 HRC. For the 13-8 stainless steel application, the VGM end mill dominated the machining result by extending tool life from seven parts to 21 parts per tool. The parts were also completed in half the time and the tool cost is also cheaper than the competitor tool. Lerma was so impressed by the VGM end mill that he decided to apply the tool to the Inconel 718 aerospace bracket application. Allied Tool & Die was previously using a high feed indexable milling cutter for the Inconel 718 aerospace bracket application. However, the amount of time and money spent on changing the inserts was less than desired.
The previous competitor tool was used at 150 SFM (45.7 m/min), 0.009 IPT (0.23 mm/t), 0.05 Aa (ap = 1.27 mm) and 0.75 Ar (ae = 19.05 mm). After reprogramming to utilize OSG’s 0.5-inch diameter 5-flute VGM carbide end mill with a 0.030-inch (0.762 mm) corner radius and 1.25-inch (31.75 mm) length of cut (EDP# VGM5-0143), the cutting parameters were changed to 250 SFT (76.2 mm/min, 2,548 min-1), 0.0022 IPT (0.056 mm/t, 713 mm/min), 0.75 Aa and 0.035 Ar. The application went from a 4-hour cycle time to just one hour and 45 minutes. Allied Tool & Die no longer had to keep stopping the machine to rotate or change inserts, which they were doing four times per part previously. By switching to the VGM end mill, the tool was loaded, and the job did not have to be tended to until the part was completed. In terms of efficiency improvement, Allied Tool & Die estimated that the tool change has generated a cost savings of $6,875 USD on the Inconel 718 aerospace bracket parts. Moreover, with a lower tooling price versus the previous milling cutter, the cost of tooling also decreased by almost $100 USD per part. With the VGM end mill, Allied Tool & Die was able to machine Inconel 718 at an astounding 250 surface feet per minute (76.2 m/min) – a speed that is only commonly seen in alloy or stainless steels, not HRSA materials. With the recent successes, Allied Tool & Die’s CNC Programmer John Hernandez decided to apply the VGM end mill into most jobs he programs. Being such a versatile tool, the VGM can be used to machine anything from common carbon steels up to the nickel alloys required by the aerospace industry.

Sacramento, CA. - Next Generation Tooling, LLC, a manufacturer's representative agency, founded in 1995 and servicing the California Nevada Arizona, Utah, Colorado and New Mexico CNC manufacturing markets has just opened TWO offices in California. Most of Next Generation Tooling's customers know them as "the Next Gen guys" according to Chris Savolainen, the Founder and President of 'Next Gen Tooling'. What was the rationale of opening not one, but two offices when the entire team has worked out of their own home offices for years? "We've grown our market service area quite a bit since we started out servicing just Northern California. We now include most of the Western States of the US. We've s been adding some of the best technical CNC application people we can find to support the unique mix of principles we represent. The products that we represent are what are considered very high performance tooling and workholding. It's some of the premiere products in our entire industry! We determined that we really needed a place to provide on-site technical training. We also needed to carry some inventory to support the unique needs of the aerospace, medical, electronics and defense industries that we support." Said Savolainen. Rob Aldama, Vice-President of Next Gen Tool picks up the story, "At first we thought that one training and showroom might be good enough, but as we started talk to our distributor, machine dealer and end-user manufacturing customers, we discovered that there was a real need for facilities in both Northern and Southern California. None of our competitors are providing the deep technical service that has helped us gain market share, so we really felt we should just take it to the next level and open two facilities." But what about the Pandemic? With the Covid-19 pandemic raging there are not a lot of companies expanding. Most are cutting costs and employees. When asked about this both Chris and Rob stated that their team of people have remained pretty busy throughout this entire period. Chris said "We get asked in to shops to provide technical support pretty often. Putting on the full body PPE suits has been kind of common for us during the past few months." Rob picked it up from there, "I think we may be some of the really select few that have been asked to come into shops because we're not just taking orders, we're reducing cycle time and we're improving efficiency" Chris jumped back in, "And maybe its a little bit self serving, We can have the equipment set-up at both locations instead of trying to bring it into a facility. It's actually a lot easier, faster and safer to bring people to one of our locations rather than try to move things with lots of sweat and heavy breathing in PPE." "Yea, We can bring people to either location and do the training. There are far less interruptions and the I think people learn a lot more, and learn it faster" stated Rob. NGT Warehouse and Training What types of training do they provide at Next Gen's new buildings? They start off with a lot of fundamentals that people running CNC machines may never had any formal training about. That's where their basic Training Classes fit in. ![]()
But they also can go much deeper with their Advanced Part Manufacturing training series

Farewell & Parting: Next Generation Tooling ends relationship with MA Ford after 22 years.9/29/2017 After 22 years, Next Generation Tooling has ended our relationship as an independent sales agent for MA Ford in the Northern California and Northern Nevada territories. Our last effective day will be September 30, 2017.
We truly appreciate and greatly value our long, successful relationship fostered by both MA Ford and NextGen since the inception of our company. We realize, with no reservation, that the wonderful people at MA Ford were a huge part of our success by working with us to develop technical solutions and will always value our memories and our personal friendships. At the outset of our relationship in the late 1990's, we worked hand-in-hand with MA Ford to introduce their products to the unique applications and high speed machining that takes place in our markets. In conjunction with the MA Ford engineering team we developed the 138 series end mills for use in aluminum and non-ferrous milling. As a result, many other end mill manufacturer's followed in the footsteps of that tool and began developing material specific tooling. Because of the unique needs of our market, we suggested the expansion of LOC and OAL from what was commonly offered in "Stub, Standard, Long & Extra Long" lengths. The 138 series end mills where the first nationally recognized brand to offer 7 different lengths of cuts as stock standard. We are very grateful to everyone at the MA Ford team who has worked with us hand-in-hand for so many years, and wish only the best for MA Ford in the future. We where very excited to meet and greet many of our customers at the 2017 Western Tool & Supply Open House. It was held at their San Jose, CA. on September 21- 22, 2017. We featured quite a few featured products from our principals during the two day event. It was great discussing lots of technical applications that machinists brought to us! NTK's industry leading line of ceramic cutting tools is expanding with new solid ceramic end mills. It's time to upgrade from carbide to this unique "SX9" SiAlON end mill which increases productivity more than 10 times over traditional end mills when machining Heat Resistant Super Alloy (HRSA) materials. NTK's durable SX9 grade can run at speeds of 2000 SFM. The line-up includes 4 and 6 flutes in inch and metric versions. The NEW SX9 SiALON Ceramic end mills are available in both a 4 flute and 6 flute configuration and can be used for slotting, pocketing, ramping, face milling, side milling and profile milliing.
