Small Diameter Coolant-Through Carbide Drills 2D · 5D · 12D · 20D · 30D
OSG Corporation has announced the release of the ADO-MICRO small diameter coolant-through carbide drill series for stable and high efficiency drilling in small diameter deep-hole applications.
Poor chip evacuation is a common complication in small diameter deep-hole drilling. Micro sludges can be easily accumulated around the outer periphery of the cutting tool, which is a key cause of abrupt tool breakage.
The ADO-MICRO features a unique double margin geometry with an extended flute and shortened end margin to enhance chip evacuation capability.
In addition to the outstanding chip ejection performance, the double margin configuration supports the straightness stability of the tool and reduces rifle marks on the inner surface of holes.
Furthermore, the ADO-MICRO features a pair of large oil holes and employs a hollow shank design to allow large coolant flow volume for trouble-free chip evacuation.
The ADO-MICRO is coated with OSG’s original IchAda coating that provides excellent surface smoothness in conjunction with high abrasion resistance and heat resistance to enable small diameter tools to achieve long tool life.
With the ADO-MICRO’s unique tool geometry and IchAda coating, non-step drilling is made possible even for deep-hole applications, enabling high processing efficiency.
The ADO-MICRO is suitable for carbon steel, alloy steel, stainless steel, cast iron, ductile cast iron, aluminum alloy, titanium alloy and heat resistant alloy. The ADO-MICRO is available from diameter 0.7 mm up to 2 mm for drill lengths 2xD and 5xD, and diameter 1 mm to 2 mm for drill lengths 12xD, 20xD and 30xD.

We've assembled a few tips on drilling that you may want to pass along to your team.
Drilling Tip 1
During drilling operations, chip formation is very important to keep an eye on. If you are getting long unbroken chip with jagged edges, your feed rate is too high. If you are getting tight spirals but the chips are not breaking apart, your feed rate is too low.
The Ideal chip shape is small tight curls, Like little "6's and 9's". When you are getting these shapes of chips then you will get best tools life and finish on your part.
Drilling Tip 2
If your drill is getting chipped only on one edge or if your drill has more wear on one cutting edge than the other, the cause could be bad run out of the drill or bad alignment of the machine.
This means one side of the drill is experiencing more axial forces than the other. If you correct the run out of the drill and alignment of machine spindle, the problem will be solved.
Drilling Tip 3
If your drill has too much run out, you will have issues such as hole expansion, bad hole perpendicularity, and poor surface finish.
Drill run out should be less than 0.0008"(0.02mm) when setting up. The run out increases with the speed, thus, when drilling a deep hole.
OSG recommends making the pilot hole 0~0.003"(0.08mm) oversize and inserting a long drill at 0~500rpm so that the drill is fitting properly in the pilot hole .
Drilling Tip 4
The V-Series HELIOS® drill is the 1st drill to process deep holes 10X-20X diameter, without pecking and without the use of internal coolant supply.
Flute form, point thinning and compound lead construction are all patented technologies developed by OSG to make this drill do what no other parabolic HSS-Co drill can.
The addition of our exclusive WXL coating technology makes non-peck drilling repeatable, even in the longest of production runs.
Drilling Tip 5
Last but not least, don't forget that now through August 31st, save 12% on select A-Drills!l
An end mill is a type of milling cutter. It is distinguished from the drill in its application, geometry, and manufacture.
End mills are used in milling applications such as profile milling, tracer milling, face milling, and plunging.
Below is a great video of how OSG makes end mills. It takes you through the process from design to the grinding operations and through inspection. Check it out!
...and below is the segment from "How It's Made" that covers the more general principles of making a HSS end mill.
You can see that OSG has a very advanced process for making their carbide end mills.

by David Aly, Aerospace Specialist, OSG Tap & Die
Just because you’ve tried one forming tap, doesn’t mean you’ve tried them all. We had the recent opportunity to prove that OSG forming taps are better than the rest.
As a supplier of custom fabricated metal products and machinery, one of our customers approached us wanting to get better chip control during their tapping operation. Located in Winona, Mississippi, they have a 92,500 square foot manufacturing facility for producing fuel tanks, hydraulic tanks and custom designed machining fixtures.
After discussing the customer’s chip control needs, I recommended OSG’s EXOTAP® NRT® Forming Tap, a more stable, thread rolling tap that makes threads by compressing the work material without creating chips. Because no chip is produced, breakage due to chip packing and bird nesting is eliminated.
The EXOTAP® NRT® also has significantly reduced friction resistance because of its special threading design and surface treatment. Made from VC-10 Powdered Metal High Speed Steel, this forming tap has a longer tool life when tapping difficult to machine materials like carbon steels, alloy steels, stainless steels and aluminum alloy.
Initially, the shop foreman, Mr. William Smith, was hesitant about using a forming tap due to a bad experience with a competitor’s brand. After I showed William a presentation and a chip flow demonstration video, he was willing to give our forming tap a chance.
We approached his staff with OSG’s EXOTAP® NRT® Forming Tap in hand. After explaining the test with the operator and reiterating that there will be no chips, we began the trial.
A few days later, I called to check in on their progress. William enthusiastically explained that he was still running the same tap. He had lost count of the number of holes produced but assured me that it was well over 1,000 holes! After such a successful run with the first test tap, he purchased more of the test size, now truly convinced that all forming taps are not created equal.
Next Generation Tooling is excited to offer some new services coming in 2015!
Below is a very fast video of our new training series on Tapping which we can present to your manufacturing team at your site.
It's a comprehensive overview of screw thread terminology, thread forms, fundamentals of threads, classes of fit, Tap basics, types of chamfers, the tapping process,tap types, screw thread inserts, helix angles, core diameters, re an hook angles, thread reliefs, pitch tolerances, H limits, Tap substrates, Surface treatment and coatings, tapping speeds, tap drill sizes.
Understanding tool geometry and selecting the right tap for different workpiece materials can help take the anxiety out of tapping operations.Many machinists have learned to dread tapping. The story goes something like this. They press cycle start and then step back because the machine is in control. If the tap should hit bottom, too bad; the cycle must be completed—no feed-hold is allowed here. If the wrong feed rate was programmed, tough luck; the feed rate override is disabled. What else is there to do but cringe as the tap enters the hole?
For example, lowering the chip load can eliminate premature wear on a tap. Defined as the load induced on any one cutting edge, chip load is typically controlled by altering the feed rate. As mentioned earlier, this is not possible when tapping but the chip load can be altered through tap selection.
OSG’s Hy-Pro tap is designed for vertical and horizontal CNC tapping. The VXL tap (left) has a fast spiral-flute design for vertical machining. The HXL tap, with a slower spiral to break up chips, is for horizontal machining.
