Drill bit FANAR HSS cylindrical for metal 3.4 mm, model W2-101811-0340

FANAR HSS cylindrical drill bit with a 3.4 mm cutting diameter is designed for drilling metal in workshops, maintenance and light fabrication tasks. Made from high-speed steel (HSS), the bit combines wear resistance with good cutting ability for a wide range of ferrous and non-ferrous metals. Its straight cylindrical shank fits standard drill chucks and is suitable for use in hand drills and drill presses.

Advantages

The high-speed steel construction provides durability and temperature resistance during continuous drilling operations. A precise 3.4 mm diameter ensures predictable hole size and repeatability when used with correct pilot alignment. The cylindrical shank offers simple mounting in keyed or keyless chucks, and the ground cutting edges deliver efficient chip removal and stable cutting performance on typical workshop metals.

Suitable for

• Drilling holes in mild steel, stainless steel and cast iron (appropriate cutting parameters required)
• Working with non-ferrous metals such as aluminum and brass
• General maintenance and repair tasks around machinery and installations
• Light fabrication and prototype work in metal workshops

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 3.4 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Intended use: drilling metal
• Suitable tools: hand drills and drill presses

How to use

Secure the drill bit in the chuck so that a sufficient length of shank is clamped to avoid slippage. Mark and center-punch the drilling position to reduce wandering, then start drilling at low speed to establish the hole. Use cutting fluid when drilling harder steels to reduce heat and prolong tool life; for softer non-ferrous metals, moderate speeds and light feed rates are usually adequate. Withdraw the bit periodically to clear chips and prevent clogging.

Usage recommendations

Use appropriate cutting speeds and feed rates for the material being drilled, and apply cutting fluid when working with hardened or stainless steels. Inspect the bit for wear before use and replace if edges are dull or the flute is damaged to maintain hole quality and safe operation.
