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.

5/64" Drill Bit for Metal – Balance of Finesse and Strength
Drill clean, precise holes in stainless steel and alloys with the 5/64" drill bit for metal. Cobalt construction delivers strength and reliability in tight spaces.
Small Size, Strong Core
When your project demands slightly more room than a 1/16" bit, the 5/64" drill bit for metal is the next logical step. This size is ideal for forming clearance holes for small screws, fine-detail fabrication, and electronics mounting tasks. Despite its small diameter, it delivers robust performance in both shop and field environments.
Common use cases include preparing pilot holes for threading, working on stainless kitchen appliances, or drilling mounting holes in automotive dashboards.
Cobalt Strength and Sharp Entry
Made from M35 cobalt steel, this drill bit resists wear and maintains its edge over prolonged use. The 118° point anglesuits its diameter perfectly, giving you controlled entry with minimal walking. This makes a huge difference when you're starting holes by hand.
This drill bit is effective on:
Stainless and carbon steel
Thin aluminum and brass sheets
Rigid plastic panels
Copper and alloy metals
Use Lubricant to Improve Results
Drilling into tough materials without lubrication can overheat small bits quickly. By using TTP CUT-IT metal cutting paste, you reduce heat, avoid breakage, and extend tool life.
Dial In the Right RPM
Using the correct speed prevents common problems like dulling or bit snapping. Use our free Speeds & Feeds Calculator to enter your material type and get the exact RPM needed for safe, efficient drilling.
Trusted by Trades, Covered by Guarantee
From repair technicians to metal fabricators, this 5/64" drill bit for metal is a staple in professional kits across the USA. If you don’t love its performance, we offer a full money-back guarantee—no hassle, just results.
