## Summary description

Tvardy HSS M35 cobalt drill bit, 12 mm diameter, designed for drilling metal. Made from high-speed steel with 5% cobalt (M35) for increased heat resistance and wear performance. Suitable for stainless steel and hard alloys, intended for use with drill presses and hand drills in workshop, industrial and maintenance tasks.

## Long description

Tvardy HSS M35 cobalt drill bit, 12 mm diameter, is engineered for reliable metal drilling where increased heat resistance and edge retention are required. Made from high-speed steel with 5% cobalt (M35), this drill bit is intended for drilling a variety of ferrous materials including stainless steel and other hard alloys. It is suitable for use with drill presses and hand drills in workshop, industrial and maintenance environments and is optimized for consistent drilling performance and longer tool life compared with standard HSS bits.
Advantages
The M35 cobalt composition provides improved heat resistance and hardness, reducing wear and preserving cutting geometry during prolonged use. The 12 mm diameter offers a balance between rigidity and cutting speed for medium-sized holes. The bit’s construction supports higher cutting temperatures, allowing faster feed rates and extended service life when used with appropriate cooling and correct drilling speeds.
Подходит для
 Сверления нержавеющей стали
 Работ с твердыми сплавами и закалёнными металлами
 Ремонтных и обслуживающих работ в мастерской и на производстве
 Использования со сверлильными станками и ручными дрелями
Key specifications
 Material: high-speed steel with 5% cobalt (M35)
 Diameter: 12 mm
 Intended materials: stainless steel, hard alloys, general ferrous metals
 Shank type: straight shank suitable for drill chucks (standard industrial shanks)
 Flute: two-flute twist geometry for chip evacuation
 Finish: ground cutting edges for accuracy and repeatability
How to use
Secure the drill bit in the drill chuck ensuring proper centring and clamping. Select a drilling speed appropriate for the work material and diameter—use reduced speeds for stainless steel and hard alloys. Apply steady feed pressure and use cutting fluid or coolant to reduce heat buildup and improve chip evacuation. Retract the bit periodically on deep holes to clear chips and prevent clogging. After use, clean the bit and store it in a dry place to avoid corrosion.
Usage recommendations
For best results when drilling stainless steel and hard alloys, use a cutting fluid and lower spindle speeds compared with soft materials. Maintain consistent feed pressure and avoid excessive side loads to preserve the cutting edge and extend tool life.
