Drill bit Proline 72230 — metal HSS 22 mm × 300 mm, 1 pc

Proline 72230 — metal HSS 22 mm × 300 mm, 1 pc is a single high-speed steel (HSS) drill bit intended for drilling metal and similar materials. With a 22 mm cutting diameter and a total length of 300 mm, this drill bit is suited for deep or through-hole drilling in workshop and industrial environments. It is designed for use with hand-held metalworking drills and drill presses and provides a consistent cutting diameter for metalworking tasks.

Advantages

The HSS material offers good hardness and heat resistance for drilling into steel and other metals while maintaining cutting edge durability. The 300 mm overall length enables deep penetration and through-hole work without the need for extensions. Engineered geometry of the flute and point promotes chip evacuation and more stable drilling when used with appropriate speeds and clamping. Supplied as a single piece, the drill bit is ready for immediate mounting and use in compatible chucks.

Suitable for

• Drilling holes in steel and non-ferrous metals
• Deep or through-hole drilling in workshop and industrial settings
• Use with metalworking drills and drill presses
• General metal fabrication and repair tasks

Key specifications

• Material: High-speed steel (HSS)
• Cutting diameter: 22 mm
• Overall length: 300 mm
• Quantity: 1 piece
• Intended materials: Metal and similar materials

How to use

Secure the Proline 22 mm HSS drill bit in a suitable chuck and ensure the workpiece is firmly clamped. Select an appropriate spindle speed and feed for the metal being drilled; lower speeds are typically used for harder steels and higher speeds for softer metals. Use cutting fluid or coolant to reduce heat buildup and improve tool life. Apply steady, even pressure and allow the drill to cut without excessive force. For deep holes, periodically withdraw the bit to clear chips and maintain coolant flow.

Usage recommendations

For best results, match drill speed and cutting fluid to the specific metal type, use secure clamping to prevent movement, and inspect the bit periodically for wear. Replace the bit when signs of significant wear or chipping appear to maintain hole quality and safety.
