Frequently Asked Questions

What materials can this cobalt drill bit cut?

Our cobalt drill bits handle stainless steel, cast iron, hardened steel, alloy steels, aluminum, copper, and more.

What speed should I use when drilling metal?

Use our Speeds & Feeds Calculator to set the correct RPM. Running too fast will overheat the bit; slower speeds preserve sharpness.

Can cobalt drill bits be resharpened?

Yes — cobalt drill bits can be resharpened, giving you long-term value.

How is cobalt different from standard HSS?

Cobalt (M35, 5%) withstands higher heat and stays sharper longer, making it ideal for harder metals compared to standard high-speed steel.

Do I need cutting paste when drilling metal?

We recommend TTP CUT-IT cutting paste for smoother drilling, cooler operation, and longer tool life.

1/16" Drill Bit for Metal – Fine Detail Meets Cobalt Power

Achieve ultra-fine precision in stainless steel and hard metals with the 1/16" drill bit for metal. Ideal for detailed work, electronics, and pilot holes.


Precision for the Smallest Jobs

The 1/16" drill bit for metal is one of the most precise tools in your toolbox. Whether you're drilling pilot holes, handling circuit board repairs, or working with delicate sheet metal, this bit delivers accuracy where it matters. Thanks to its slim diameter, it’s commonly used in electronics, watchmaking, and fine-detail fabrication.

Despite its small size, this cobalt bit offers serious cutting power. You can count on it to maintain shape and sharpness while producing accurate, clean holes even in tough metals.


Optimized for Controlled Drilling

This bit is crafted from M35 cobalt steel, which offers higher heat resistance and durability than traditional high-speed steel. Its 118° point angle is perfect for such a fine size, ensuring clean penetration without snapping or walking. While larger sizes benefit from a 135° split point, 1/16" is best suited to the 118° angle for fine entry.

Suitable materials include:

  • Stainless steel

  • Mild steel and alloy steel

  • Sheet metal and thin tubing

  • Copper and brass

  • Plastic housings and circuit panels

This bit excels in light touch, high-precision jobs.


Extend Lifespan with Lubrication

Using a lubricant helps reduce friction and prevent heat buildup—especially important for smaller diameter bits. We recommend applying TTP CUT-IT metal cutting paste before drilling. It ensures smoother cuts, longer bit life, and better hole quality.


Use the Right Speed—Avoid Bit Breakage

Speed matters. To prevent overheating or snapping such a fine bit, use our Speeds & Feeds Calculator to dial in the optimal RPM. Small bits should be run slower in tough metals, especially stainless steel.


Backed by Professionals, Guaranteed

This 1/16" drill bit for metal is used daily by aerospace engineers, electronics technicians, and metalworkers who require the finest detail. And with our money-back guarantee, there’s no risk. If it doesn’t perform to your expectations, we’ll refund your purchase—simple as that.
