Drill bit FANAR HSS cylindrical 11.5 mm for metal, model W2-101811-1150

The FANAR HSS cylindrical drill bit with a nominal diameter of 11.5 mm is designed for drilling metal and producing straight, accurate holes. Made from high-speed steel (HSS), this drill bit is suitable for general machining of steel, iron and other ferrous materials. Its cylindrical shank allows secure clamping in hand drills and drill presses, making it appropriate for both manual and machine operations where dimensional accuracy is required.

Advantages

The HSS material provides good wear resistance and heat tolerance during drilling of hard metals; the cylindrical shank ensures stable grip in chucks and reduces slippage; the 11.5 mm nominal diameter is suitable for medium-size through-holes and fits common drilling setups; the geometry of the cutting edges is optimized for metal cutting to deliver straight holes with consistent performance when used with appropriate speeds and lubrication.

Suitable for

• Drilling steel components and structural parts
• Creating holes in cast iron and ferrous alloys
• Workshop and maintenance tasks with hand drills or drill presses
• Preparatory drilling for tapping or fastening operations

Key specifications

• Material: High-speed steel (HSS)
• Nominal diameter: 11.5 mm
• Shank type: Cylindrical
• Intended use: Metal drilling (steel, iron and other ferrous materials)

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring the cylindrical shank is fully seated and tightened. Select an appropriate spindle speed for the material being drilled and apply cutting fluid or lubricant when working with steel to reduce temperature and prolong tool life. Start drilling with steady, moderate feed pressure, withdraw periodically to clear chips if drilling deep holes, and finish by reducing speed near hole exit to avoid burrs. After use, clean chips from the flutes and store the bit in a dry place to prevent corrosion.

Usage recommendations

For best results when drilling steel and similar ferrous materials, use cutting fluid and match drill speed to material hardness; avoid excessive feed force to prevent premature tool wear and maintain hole straightness.
