Stocked Globally Stocked Note: For drill diameter selection, use the method outlined below. Straight Fluted & Spiral Fluted Taps: 0.46 (TapØ) < (DrillØ) < 0.75 (TapØ). Spiral Pointed Taps: 0.6 (TapØ) < (DrillØ) < 0.75 (TapØ). Available Upon Request; MOQ May Apply
1. Broken Tap Check how tap is broken. If any portion of the tap is
protruding, grind the damaged surface of the tap flush with the workpiece. This will allow the damaged tap to be drilled easier.
Cutting Conditions and Procedures to Note
2. Centering of Drill Position the drill over the center of the tap. Please make sure both the workpiece and drill are properly secured. Make an initial light drill approach, and then quickly retract the drill. For this step, do not use lubrication. 3. Hole Processing Drill the hole at a fixed feed and speed, stopping the operation occasionally to remove broken chips. In addition, use plenty of high quality cutting oil. 4. Chip Removal Once the tap has been broken up, the remaining portions of the tap can be removed. For best results, use a scriber. Once the hole is cleaned, tapping can be resumed.
1. Use a drilling speed of 65-80SFM. 2. 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.
