Hymnorq 7/32" Cobalt Steel Twist Drill Bits for Metal, Pack of 10PCS

If you want to drill holes in hard metals such as bronze, cast iron, stainless steel, titanium or welding seams, this set of Hymnorq metric M35 cobalt-containing twist drill bits will be a good choice.

These M35 cobalt drill bits are made with a combination of M2 high-speed steel and 5% cobalt. Therefore, they are much harder than ordinary high-speed steels and can be sharpened relatively easily with cutting fluid while retaining their strength and durability.

Please note that the M35 cobalt drill bit is not suitable for low-intensity operations such as drilling through wood, plastic, etc. Don't use M35 cobalt bits on hardened steel, high-carbon steel, and heat-treated steel.

M35 cobalt steel drill bits can be mounted to handheld devices without fear.

Thanks to this 5% cobalt, this drill has a higher melting point, suitable for use in high-temperature conditions.

The amber color on the surface of the drill bit is baked to distinguish between different kinds of drill bits. When the surface color wears and the drill bit becomes blunt, they can be resharpened and continue to be used.

The 135°quick-cut split points are self-centering and can penetrate quickly with less pressure. The bits will not "walk" or "wander".

The classic straight shank design allows for accurate centering, fit for standard drill chucks and regular round collet chucks.

The set includes 10 pcs of 7/32 inch M35 grade cobalt steel twist drill bits, packed in a plastic case for easy transport to your worksite.
