Bordo Metric Spiral Point Tap and Drill Set M3-M12 HSS-Co, 14pcs

Product Features

• M3-M12 HSS-Co5 (Cobalt) Metric Coarse Spiral Point (Gun Nose) machine tap set with HSS tapping drills.
• Cobalt HSS taps are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
• Gun nose taps have straight flutes supplemented by angular cutting faces at the lead.
• The design of the cutting portion propels the swarf ahead of the tap leaving the flutes clear for the flow of coolant to the cutting teeth.
• Primarily designed for use in through holes, these taps can be used in blind holes provided that there is ample clearance beyond the threaded section to accommodate the swarf.
• The advantages of a gun nose tap are the shearing action of the angular cutting faces, which produces a fine finish on the threads and shallower flutes. This allows a stronger cross section throughout the tap.
