Pilot Tap with Cobalt Titanium-Coated HSS Drill Bit for Stainless Steel, Aluminum, Copper, Iron, Square Shank

About this item

• Size Options: M3-M12 spiral pilot taps with drill diameters of 0.1 in (2.5 mm), 0.13 in (3.3 mm), 0.17 in (4.2 mm), 0.2 in (5 mm), 0.27 in (6.8 mm), 0.33 in (8.5 mm), and 0.4 in (10.2 mm), with thread pitches of 0.5 mm, 0.7 mm, 0.8 mm, 1 mm, 1.25 mm, 1.5 mm, and 1.75 mm. Each size corresponds to a specific hole diameter, meeting various drilling and tapping needs
• HSS with Cobalt + Titanium Coating: the drill tips are made of high-quality cobalt-containing high-speed steel (HSS), enhancing red hardness and wear resistance for stable performance under high temperature and pressure. A high-hardness titanium coating further strengthens the surface while providing excellent lubrication and corrosion resistance
• Through-Hole Spiral Flutes: the pilot taps feature spiral flutes at the tip for chip evacuation, suitable for through-hole tapping down to the bottom, preventing chip clogging
• Applicable Materials: ideal for use on stainless steel, mold steel, aluminum, copper, and other metals
• Square Shank Design: the square shank is compatible with drill presses, tapping machines, and automatic machines. Due to the high hardness of the titanium-coated taps, hand drills are not recommended for tapping. M2 - M6 have pointed tips; M8 and above have flat tips
