Drill bit Tvardy HSS for metal 10.50 mm (model T02105)

Tvardy HSS for metal 10.50 mm (model T02105) is a high-speed steel twist drill bit designed for drilling round holes in a variety of metal materials. Made to HSS standards, the bit combines hardness and toughness to maintain cutting edge life under typical workshop and maintenance loads. The 10.50 mm diameter and standard 118° point geometry suit general-purpose metalworking with hand-held drills and drill presses.

Advantages

The HSS material provides wear resistance and thermal stability appropriate for drilling mild steel, cast iron and non-ferrous metals at moderate speeds. A precisely ground flute geometry ensures efficient chip evacuation and stable cutting action, while the 118° point reduces walking and helps start holes accurately without special pilot tooling. The shank is compatible with common drill chucks, enabling quick installation and reliable grip during operation.

Suitable for

• Drilling holes in mild and medium-hard steels
• Fabrication and maintenance tasks in workshops
• Drill press and hand-held electric drill applications
• Repairs on machinery and metal assemblies

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 10.50 mm
• Point angle: 118° (standard)
• Type: Twist drill bit for metal
• Compatibility: Suitable for hand-held drills and drill presses

How to use

Select an appropriate drilling speed for the metal being cut and secure the workpiece to prevent movement. Mark the drilling position and, if required, center-punch to prevent walking. Fit the drill bit firmly in the chuck and ensure it is concentric. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material while applying steady pressure. Use cutting fluid or coolant for improved life and better chip removal when working with harder metals or extended drilling sessions. Withdraw the bit periodically to clear chips if drilling deep holes.

Usage recommendations

For best results, use cutting oil when drilling steel and adjust spindle speed according to material hardness: lower speeds for harder alloys, higher speeds for softer non-ferrous metals. Inspect the bit for wear or chipping before use and replace when the cutting edge becomes blunt to avoid poor hole quality and increased load on the drill motor.
