Drill bit FANAR HSS cylindrical 12.5 mm — metal drilling, model W2-103811-1250

Cylindrical HSS drill bit FANAR 12.5 mm is designed for precise metal drilling in workshop and industrial settings. Made of high-speed steel, this 12.5 mm diameter drill is intended for creating holes in steel, iron and other ferrous and non-ferrous metals. The cylindrical shank fits standard drill chucks, providing straightforward mounting and stable rotation for general metalworking tasks.

Advantages

The high-speed steel construction offers consistent wear resistance and heat tolerance during continuous drilling operations. The cylindrical shank ensures compatibility with most drill chucks and supports secure clamping. The 12.5 mm cutting diameter provides a balance between hole size and material removal rate, suitable for common workshop and industrial applications. The geometry is optimized for efficient chip evacuation and stable cutting when drilling metal materials.

Suitable for

• Drilling holes in steel and iron components
• Working with non-ferrous metals such as aluminum and brass
• General-purpose metalworking in workshops and maintenance shops
• Industrial production tasks requiring repeatable through-holes

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Nominal cutting diameter: 12.5 mm
• Intended material: ferrous and non-ferrous metals
• Typical applications: through-holes and general metal drilling

How to use

Fit the cylindrical shank into a properly rated drill chuck and tighten securely to prevent slippage. Select an appropriate spindle speed and feed rate for the metal being drilled; lower speeds are generally advised for harder steels while higher speeds suit softer non-ferrous metals. Use cutting fluid or coolant to reduce heat and improve tool life when drilling thicker or harder materials. Apply steady, even pressure and allow the drill to advance at a controlled rate to avoid overheating or breakage.

Usage recommendations

For best results, pre-center holes with a pilot drill for large-diameter or deep drilling, and use appropriate cutting fluid. Inspect the drill bit regularly for wear and regrind or replace when cutting performance declines to maintain hole quality and operator safety.
