About this item
- 【M35 COBALT HIGH SPEED STEEL】Made of premium M35 cobalt high speed steel with 5% cobalt content, offering excellent wear resistance, high hardness, and long service life for repeated use.
- 【135° SPLIT POINT DESIGN】The 135° split point tip prevents "walking" on the material surface, eliminating the need for a center punch and enabling quick, precise penetration with less pressure.
- 【FULLY GROUND SPIRAL FLUTES】 Fully ground spiral flutes clear chips quickly, reduce friction and heat buildup, enabling smoother, faster drilling performance even in hard metals.
- 【VERSATILE DRILLING APPLICATIONS】 Ideal for drilling holes in stainless steel, steel, cast iron, copper, aluminum alloy, galvanized pipe, wood, and other soft metals. Not suitable for glass or ceramic materials.
- 【5-PIECE SET WITH STORAGE CASE】 Package includes 5 pieces of 3/8" cobalt drill bits (total length 5", flute length 3-5/8"). Fits most standard power drills and comes with a portable plastic case for easy storage and organization.
