Drill bit FANAR HSS cylindrical 10.2 mm, model W2-103811-1020

FANAR HSS cylindrical 10.2 mm drill bit (model W2-103811-1020) is a high-speed steel metalworking bit intended for drilling precise 10.2 mm holes in steel and a range of other metals. The bit features a cylindrical shank for reliable clamping in drill chucks and drill presses, and a ground cutting geometry appropriate for general-purpose metal drilling in workshop, industrial and maintenance settings.

Advantages

The HSS material provides a balance of hardness and toughness for efficient cutting in common ferrous and non-ferrous metals. The cylindrical shank ensures stable grip and compatibility with standard chucks and arbors, reducing runout and improving hole accuracy. The bit’s diameter is held to tolerances suitable for repeatable 10.2 mm hole production, and its ground flutes facilitate chip evacuation during continuous drilling.

Suitable for

• Drilling 10.2 mm holes in steel and iron
• Metal fabrication and sheet metal work
• Workshop and maintenance drilling with drill presses or hand-held drills
• Industrial production where consistent hole diameter is required

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 10.2 mm
• Shank type: cylindrical
• Application: metal drilling (ferrous and non-ferrous)
• Suitable mounting: drill chucks and drill presses

How to use

Select appropriate cutting speed and feed for the metal being drilled and secure the workpiece with clamps or a vice. Fit the cylindrical shank into the drill chuck and tighten firmly to minimize slippage. Start drilling at low speed to establish the pilot and then increase speed as appropriate for material and machine capability. Use consistent pressure, withdraw periodically to clear chips if necessary, and apply cutting fluid or lubricant for improved tool life and hole quality when drilling harder metals.

Usage recommendations

Use cutting oil or appropriate lubricant when drilling hardened steels, maintain proper speeds to avoid overheating, and replace the bit if wear causes oversized or rough holes. For best accuracy, use a drill press and ensure the chuck and spindle runout are within acceptable limits.
