Drill bit FANAR HSS cylindrical 8.3 mm for metal, model W2-101811-0830

FANAR HSS cylindrical 8.3 mm drill bit is designed for precise drilling of metal. Made of high-speed steel (HSS), the cylindrical shank provides a secure, straight fit in hand drills and drill presses. The bit is suitable for use on a range of ferrous and non-ferrous metals in workshop, maintenance, and fabrication environments where reliable cutting performance and resistance to heat are required.

Advantages

The high-speed steel construction ensures good wear resistance and maintains cutting edge hardness at elevated temperatures encountered during metal drilling. The cylindrical shank offers compatibility with common chucks and simplifies alignment in both portable drills and bench-mounted drilling machines. The 8.3 mm diameter provides a middle range size appropriate for through-holes, pilot holes for larger fasteners, or clearance holes for bolts and fittings.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and other non-ferrous metals
• Workshop fabrication and assembly tasks
• Maintenance and repair operations requiring straight-shank drill bits
• Use in hand drills and drill presses with compatible chuck capacity

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank
• Drill diameter: 8.3 mm
• Intended use: metal drilling (ferrous and non-ferrous)
• Compatibility: suitable for hand drills and drill presses with matching chuck

How to use

Select a drill or press with a chuck capable of securely holding an 8.3 mm straight shank. Mark the drilling point and, if required, center-punch to reduce bit wandering. Use appropriate cutting speed and feed for the specific metal being drilled; apply steady pressure and allow the bit to cut rather than forcing it. Use cutting fluid or coolant when drilling harder steels to reduce heat and prolong bit life. After drilling, clear swarf from the hole and inspect the bit for wear before further use.

Usage recommendations

For best results, match cutting speed and lubrication to the workpiece material: lower speeds and proper cutting fluid for stainless and hardened steels, higher speeds for aluminum and softer alloys. Replace the bit once wear or chipping degrades hole quality to maintain accuracy and safety.
