Drill bit FANAR W21018111300, cobalt metal drill, cylindrical shank, 13 mm

FANAR W21018111300 cobalt metal drill bit with a 13 mm cutting diameter and a cylindrical shank is engineered for drilling through hard and heat-resistant metals. The cobalt alloy construction improves strength, hardness and thermal stability compared with standard high-speed steel, enabling reliable performance in heavy-duty machining operations. The cylindrical shank ensures secure clamping in hand drills and drill presses used for metalworking, maintenance and fabrication tasks.

Advantages

The cobalt composition increases wear and heat resistance, extending tool life during prolonged drilling in stainless steel, heat-treated alloys and other tough materials. The 13 mm diameter provides a balance between hole size and rigidity, reducing chatter and improving hole accuracy. Its cylindrical shank offers straightforward mounting in standard chucks and collets, facilitating quick setup and consistent concentricity.

Suitable for

• Drilling stainless steel and other hard alloys
• Industrial maintenance and repair operations
• Fabrication and metalworking shops
• Use in hand-held drills and drill presses

Key specifications

• Cutting diameter: 13 mm
• Material: cobalt alloy (high-temperature resistant)
• Shank type: cylindrical
• Intended use: metal drilling, including hard and heat-treated steels

How to use

Select appropriate cutting speed and feed for the workpiece material, reducing speed for stainless and heat-treated steels. Secure the workpiece firmly and clamp the drill bit in a suitable chuck or collet. Use cutting fluid or coolant to improve heat dissipation and chip evacuation. Apply steady pressure and avoid excessive side loading to maintain tool life and hole accuracy. Retract periodically to clear chips when drilling deep holes.

Usage recommendations

For best results when drilling hard metals, use moderate spindle speeds, appropriate cutting fluid, and a rigid setup. Regularly inspect the point geometry and replace the drill when the cutting edges become worn to prevent workpiece damage.
