Drill Bit Verto HSS cylindrical 10 mm set of 5 (model 60H090)

Drill Bit Verto HSS cylindrical 10 mm set of 5 (model 60H090) is a set of five high-speed steel (HSS) twist drills designed for metalworking. Each drill has a 10 mm diameter and a cylindrical shank for use in standard chucks and drill holders. The set is intended for workshop and repair tasks where accurate, repeatable drilling in steel and other metals is required.

Advantages

The HSS material provides good hardness and heat resistance for cutting metals at moderate speeds. Cylindrical shanks ensure secure clamping in chucks and reduce slippage during drilling. A uniform 10 mm diameter across the set simplifies tool selection for repeated operations. The set format gives immediate availability of spare bits for continuous work and reduces downtime in maintenance or production environments.

Suitable for

• Drilling holes in carbon steel and mild alloys
• Workshop maintenance and repair tasks
• General metal fabrication and assembly operations
• Use with hand-held drills and bench drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight shank) compatible with standard chucks
• Diameter: 10 mm
• Quantity in set: 5 pieces
• Intended use: drilling metal (steel and similar metals)

How to use

Select an appropriate cutting speed, feed rate and coolant based on the metal being drilled. Secure the workpiece firmly and mount the cylindrical shank in the drill chuck, ensuring concentric clamping. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and tool condition. For prolonged drilling or harder materials use cutting fluid to reduce heat and extend tool life. Replace worn bits from the set as needed to maintain hole quality.

Usage recommendations

For best results when drilling steel, use moderate spindle speeds and steady, moderate feed. Apply cutting fluid for improved cooling and chip evacuation. Regularly inspect tips for wear or chipping and re-sharpen or replace drills to preserve accuracy and prevent workpiece damage.
