Are you pecking in your Stainless, Titanium or Nickel Alloy workpiece and getting excessive wear and chipping on your tool?

These materials are easily work-hardened. Every time the cutting edges engaged and disengaged (pecking), the part's surface hardness is increased. This action makes subsequent hole processing more difficult and damaging for the tool.

Pecking should be reserved for special drilling cases such as some deep hole drilling (>10D depths) and in cases where chips cannot be broken despite adjustments to cutting conditions.

For peck-free drilling, try OSG’s EXOCARB® ADO-SUS (list 5200 & 5210) for Stainless and Titanium Alloy applications!

Ready for your PROtip for this week?

When tapping with tension-compression holders, spiral-flute taps may have a tendency to pull themselves forward, resulting in oversize threads due to overfeeding. Spiral-point taps tend to push themselves backward, resulting in undersized threads due to underfeeding.

Overfeeding with a spiral-flute tap can be corrected by reducing the program feed per rev by 5-10%, while underfeeding with a spiral-point tap can be corrected by increasing the program feed per rev by 5-10%.

For further questions regarding taps, please contact Customer Service at 800-837-2223

Ready for your PROtip of the week??

In drilling operations 10D and deeper, it is recommended to drill a pilot hole up to 3D depth to ensure hole quality, straightness and roundness. When inserting the long drill into the pilot hole, the spindle speed should be 0-500 RPM for smooth entry with minimal runout.

Once at the depth of the pilot hole, increase the spindle speed to the recommended RPM and begin cutting. After reaching the desired depth retract the drill back to the 3D depth, reduce spindle speed to 0-500 RPM and finish removing the drill from the hole.

For any drilling questions, please contact our Customer Service department at 800-837-2223.

The newly expanded EXOCARB® thread mills now includes longer lengths, miniature mills and coolant-fed thread mills.

All mills now utilize OSG's premium sub-micrograin carbide for hardness, helical flutes for free cutting action and our EXO multi-layered coating for ultimate wear resistance and tool life.

A Thread Milling: How-To Guide and ThreadPro software can be viewed and downloaded at www.osgtool.com/ThreadPro.

Here's your PROtip of the week:

Are you experiencing chatter when milling into corners?

Chatter significantly reduces tool life and leaves you with a poor surface finish. Milling into corners commonly results in chatter as more material is being engaged by the tool. To reduce this chatter, select an end mill with a radius smaller than that of the corner to be machined, then program a continuous tool path along the radius rather than turning a 90 degree angle at the corner.

Do you have other machining questions? Contact OSG’s knowledgeable customer service department or engineering team at 1-800-837-3334

Here's your PROtip for the week:

Is it possible you are overworking your tap and losing tool life?

Utilizing an appropriate percentage of thread (dictated by the tap drill size) is important when it comes to maximizing the life of the tap. OSG recommends using approximately 65% of thread for most commercial applications. Several exceptions do apply such as low tensile strength materials, thin work pieces and hardened materials.

For free-cutting materials like aluminum and thin work pieces (depth less than 1xD), we recommend increasing the percentage of thread to 70-80%.

For hardened steel applications (>50HRC), we recommend decreasing the percentage of thread to as low as 55%.

For your convenience, OSG has created a Tap Drill Size Chart to help with all of your applications! Check it out at: www.osgtool.com/TappingGuide.
