Cobalt Drill Bit Set 29 Pcs

This VEVOR cobalt drill bit set contains 29 pieces made from M35 high-speed steel with 5% cobalt content. It is designed for professional work and home DIY projects requiring precise drilling across a variety of materials. The set includes a storage case for organisation and portability.

135° Split Point Geometry

The 135° quick-cut point provides automatic centering and reduces bit drift during operation. A fully ground design maintains sharp cutting edges while the twisted structure clears chips efficiently. These features work within the limits of the split point geometry to enhance drilling speed in compatible materials.

HRC 6570 Hardness Capacity

With a hardness rating of HRC 6570, the bits handle steel, stainless steel, aluminum, copper, wood and plastic. The M35 composition delivers strength for heavy-duty applications while maintaining edge retention. Users needing larger diameters or specialised coatings beyond the 29-piece range will require additional tooling.

Questions about this item

How do I decide which of the 29 bits to use for a specific job?

The set covers a full range of diameters so you can match the bit to the hole size you need; the 135° split point centres itself and clears chips quickly across all sizes.

What does the HRC 6570 hardness rating mean once the bits are in my drill?

It indicates very high wear resistance from the M35 steel with 5% cobalt, so the cutting edges stay sharp longer in steel, stainless steel and other hard materials.

What interface do these bits use and what limits does it impose?

They have a standard straight shank that fits any three-jaw drill chuck; the shank diameter of each bit determines the maximum chuck capacity required.
