Use a water soluble oil with high density (5 to 10 times dilution). 2. Tight clamping is critical. 3. For drilling depth > 3D, use a step feed. 4. For materials susceptible to chip packing in the flute, apply a step feed. List 5172 - EXOCARB® XH WorkMaterial Broken Taps & Drills DrillingSpeed 65-80 SFM Drill Dia.

Hand feed of 0.0005~0.001 in/rev is normal. 3. Use a rigid holder. 4. Select a high quality cutting oil and apply in sufficient amounts. 5. This tool should not be used to drill soft steels, aluminum alloys or other soft materials. 6. Resharpening should be done periodically. 7. For through hole processing of heat treated steels, use a spare piece of material underneath the material being drilled as this will prevent breakage caused by sudden torque. 8. Cannot be used to remove forming taps. 304 Drilling Technical WWW.OSGTOOL.COM
