Drill bit Tvardy HSS M35 cobalt for metal 13 mm

Tvardy HSS M35 cobalt drill bit, 13 mm diameter, is designed for drilling metal with improved heat resistance and wear performance. Manufactured from high-speed steel with an M35 cobalt alloy, this 13 mm metal drill bit is suitable for both hand drills and drill presses. It is intended for use on stainless steel, alloyed steels and other hard metals in workshop and industrial environments, providing a durable cutting edge for extended drilling tasks.

Advantages

The M35 cobalt composition increases hardness at elevated temperatures and extends the life of the cutting edge when drilling hard metals. The 13 mm diameter offers a balance between rigidity and material removal rate, reducing flex and improving hole precision. Compatible with common drill chucks, this HSS M35 bit maintains consistent performance in repeated operations and resists wear better than standard high-speed steel bits.

Suitable for

• Drilling stainless steel components and sheet metal
• Working with alloyed and hardened steels
• Workshop and industrial metal fabrication
• Use in hand-held drills and drill presses

Key specifications

• Material: High-speed steel with M35 cobalt alloy
• Diameter: 13 mm
• Intended use: Metal drilling, including stainless and alloyed steels
• Compatibility: Standard drill chucks for handheld drills and drill presses
• Performance characteristics: Improved heat resistance and wear resistance for prolonged drilling

How to use

Select an appropriate drill speed and coolant/lubricant based on the metal type and thickness. Secure the workpiece firmly in a vise or clamp before drilling. Fit the 13 mm HSS M35 cobalt bit into the drill chuck and tighten securely. Start drilling at a moderate speed, applying steady pressure; for stainless and hardened steels, use lower speed and periodic coolant to reduce heat buildup. Withdraw the bit occasionally to clear chips and avoid clogging. After use, clean chips from flutes and store the bit dry to prevent surface corrosion.

Usage recommendations

For best results on stainless and alloyed steels, use cutting fluid or oil and moderate spindle speeds. Avoid excessive feed pressure that can cause overheating; allow the cobalt bit to do the cutting. Replace the bit when the cutting edge shows significant wear to maintain hole accuracy and reduce risk of workpiece damage.
