15-Piece Yellow Coated M35 Cobalt Twist Drill Bits for Precision Drilling

Product Information

High Hardness and Sharp Cutting Edge

M35 cobalt alloy material provides excellent hardness and wear resistance, ensuring that the drill bit cuts smoothly and effectively when processing hard materials.

Efficient Chip Removal Design

The drill bit design optimizes the chip removal path, which can effectively reduce cutting resistance, thereby improving drilling efficiency and reducing friction and heat accumulation.

Wide Application

Especially suitable for drilling steel, stainless steel, iron and other hard materials, it is widely used in industrial manufacturing, maintenance and DIY projects.

Fully Grinded Design

The fully polished surface of the drill bit improves the accuracy and stability of drilling, avoids drill bit deflection, and ensures drilling consistency.

Baked Yellow Surface Treatment

The yellow painted surface is not only beautiful, but also improves the corrosion resistance of the drill bit and prolongs its service life.
