Champion DT22HEX-M4X.7-IPAC Hex Shank (1/4 Inch) Metric Combo Drill/Tap Ipac

One-step operation greatly saves processing steps and improves working efficiency. Suitable for processing holes. Used for tapping aluminum, die steel, stainless steel, bronze, hard plastics, etc.. Recommended feed rate: general steel: 6-15m/min; harder steel: 5-10m/min; stainless steel: 2-7m/min; cast iron: 8-10m/min. Quick change 1/4-inch hex shank can be used on power tools more easily and securely. A tapered end on hex shank can prevent excessive tapping. It exceeds the tap to prevent thread breakage from over-drilling. Titanium coating provides excellent corrosion resistance, greatly improves wear resistance and hardness, and reduces the coefficient of friction. Use on drilling machines, tapping machines, CNC and milling machines. The torque caused by too fast feed speed is too large, which can easily cause the tap to break. Taps are prone to chipping or breaking due to speed overload or non-vertical tapping. Combination Drill and Tap Bit: Thread Size: M4 x 0.7; Hex Shank Size: 1/4. Wide Applications: Suitable for processing blind holes. Features: Self-centering point, do not need assistant center drilling or center punching. Titanium Coating: Titanium coating provides excellent corrosion resistance, greatly improves wear resistance and hardness, and reduces the coefficient of friction. Tips: Use on drilling machines, tapping machines, CNC and milling machines.
