Drill bit FANAR HSS cylindrical 12 mm for metal, model W2-103811-1200

FANAR HSS cylindrical drill bit 12 mm is designed for drilling metal and general-purpose workshop tasks. Made of high-speed steel, the 12 mm diameter bit features a cylindrical shank for use in hand drills and drill presses. It is suitable for creating through and blind holes in steel and non-ferrous metals during maintenance, fabrication and routine machining operations.

Advantages

The high-speed steel construction offers good wear resistance and retains cutting performance at typical metalworking temperatures. The cylindrical shank allows secure clamping in standard three-jaw chucks and drill presses. The 12 mm diameter is a common size for structural and maintenance work, providing a balance between cutting stability and material removal rate. The geometry is optimized for metal drilling to reduce walking on flat surfaces and to provide consistent hole quality.

Suitable for

• Drilling through and blind holes in steel and non‑ferrous metals
• Maintenance and repair tasks in workshops and industrial settings
• Fabrication, assembly and general metalworking operations
• Use with hand drills and bench or pillar drill presses with cylindrical chucks

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 12 mm
• Shank type: cylindrical shank for standard chucks
• Application: drilling in steel and non‑ferrous metals
• Suitable hole types: through holes and blind holes

How to use

Secure the drill bit in the chuck so the cylindrical shank is clamped firmly and runs true. Select an appropriate spindle speed and feed rate for the diameter and workpiece material; use lower speeds for harder steels and higher speeds for softer non‑ferrous metals. Apply cutting fluid or lubricant when drilling steel to reduce heat and extend tool life. Start drilling with light pressure to establish the point, then increase feed to steady cutting while maintaining coolant flow. Clear chips regularly to prevent clogging and inspect the bit for wear or damage before continued use.

Usage recommendations

For consistent results and longer tool life, use recommended cutting speeds for HSS in the specific material, apply proper lubrication when machining steels, and avoid excessive side loads. Replace the drill bit when cutting edges are visibly worn or when hole quality deteriorates.
