High-Speed Steel M35 (Cobalt 5%) drill bit set designed to effectively drill tough and high tensile materials. Ideal for stainless steel, cast iron, superalloys, titanium alloys, rigid plastics, and wood.
135° split point with a round straight shank for self-centering; prevents walking and ensures precise, faster drilling performance.
Double back Angle and full grinding process design helps clear particles faster, decreasing friction and heat for cooler operation.
Comes with a portable bucket for easy organization and transport, suitable for professional woodworkers, handymen, or builders.
What is the benefit of M35 Cobalt High-Speed Steel?
M35 contains 5% Cobalt, which significantly increases the heat resistance and hardness of the drill bit, making it capable of drilling through tough metals like stainless steel and cast iron.
What does the 135° split point do?
The 135° split point allows the drill bit to start cutting immediately upon contact. It prevents the bit from "walking" across the surface, ensuring higher precision and eliminating the need for a center punch.
Can these bits be used for wood and plastic?
Yes, while they are optimized for hard metals, they perform exceptionally well on rigid plastics, wood, and masonry materials.
What size range is covered in this 29-piece set?
The set covers a wide range from 1/16" up to 1/2" in 1/64" increments, providing a complete solution for various drilling needs.
Does the set come with a storage case?
Yes, the set includes a portable round bucket case that keeps the bits organized and can be easily carried or hung for convenient access.
What is the surface treatment of these drill bits?
They feature a dual Amber and Black Oxide finish, which helps in lubrication and chip removal while providing excellent corrosion resistance.
