Drill bit FANAR cobalt solid cylindrical 3.6 mm W2-101811-0360

Cobalt solid cylindrical drill bit FANAR, diameter 3.6 mm (model W2-101811-0360) is a precision cutting tool designed for drilling hard and heat-resistant materials. The bit is made from high-cobalt alloy to provide improved hardness and hot hardness compared with standard high-speed steels. Its cylindrical shank fits standard drill chucks and portable drills, making it suitable for both production environments and maintenance or repair tasks that require accurate through-holes and pilot holes.

Advantages

The cobalt construction offers enhanced wear resistance and maintains cutting performance at higher temperatures, reducing the risk of rapid dulling during extended drilling operations. The solid design ensures consistent concentricity and rigidity for improved hole quality, while the cylindrical shank provides compatibility with most drill chucks. The 3.6 mm diameter is well suited for precise pilot holes and small through-holes in metals and other tough materials.

Suitable for

• Drilling stainless steel, hardened steels and other high-strength metal alloys
• Creating pilot holes for tapping or reaming in production and repair work
• Maintenance and machining tasks in workshops and industrial settings
• Use with hand-held portable drills and bench drill presses with standard chucks

Key specifications

• Material: high-cobalt alloy (cobalt-enhanced high-speed steel)
• Type: solid cylindrical drill bit
• Diameter: 3.6 mm
• Shank: cylindrical, compatible with standard chucks
• Primary use: drilling hard and heat-resistant metals

How to use

Secure the drill bit in a properly tightened standard drill chuck, ensuring the shank is inserted fully and aligned concentrically. Select an appropriate cutting speed and feed rate for the material being drilled; lower speeds and steady feed are recommended for hardened materials to minimize overheating. Use cutting lubricant or coolant when drilling metals to extend tool life and improve chip evacuation. Apply steady pressure, avoid excessive axial force that could cause breakage, and clear chips frequently for accurate hole geometry.

Usage recommendations

For best results when drilling stainless steel or hardened alloys, use a suitable cutting fluid, moderate speed, and firm clamping of the workpiece. Inspect the bit for wear before extended use and replace if chipping or bluntness is observed to maintain hole quality and operator safety.
