Drill bit set GRAPHITE HSS for metal, cylindrical shank, 1 mm, 10 pcs

Set of 10 GRAPHITE HSS drill bits for metal, cylindrical shank, 1 mm diameter, designed for precise drilling in light to medium metalworking tasks. These high-speed steel bits are intended for use in hand drills and drill presses and provide consistent, clean holes in various ferrous and non-ferrous metals. The compact set includes ten identical 1 mm bits, offering replacement options for repetitive work and small-scale fabrication, repairs, or hobby applications.

Advantages

The GRAPHITE HSS material ensures elevated hardness and wear resistance compared to standard carbon-steel bits, supporting longer cutting life when used at appropriate speeds and with suitable cooling. The cylindrical shank fits standard drill chucks without the need for adapters and enables quick bit changes. Uniform 1 mm diameter across the set simplifies inventory for precision tasks and reduces downtime when a bit becomes blunt or damaged.

Suitable for

• Drilling small-diameter holes in sheet metal and thin plates
• Precision work in metal fabrication and model making
• Workshop repairs and maintenance tasks
• Use with hand drills and drill presses for light to medium duty
• Hobby projects requiring fine metal drilling

Key specifications

• Quantity: 10 pieces
• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank suitable for standard chucks
• Diameter: 1 mm
• Application: Metal drilling (ferrous and non-ferrous light to medium thickness)

How to use

Secure the 1 mm HSS bit in the drill chuck and tighten firmly to avoid slippage. Mark the drill point on the workpiece and, for greater accuracy, use a center punch before drilling. Select an appropriate spindle speed: higher RPMs for small-diameter bits, but reduce speed if drilling harder metals. Apply steady, moderate feed pressure and, when possible, use cutting fluid or light oil to reduce heat and extend bit life. Withdraw the bit occasionally to clear chips and prevent clogging.

Usage recommendations

For best results, match cutting speed and lubrication to the metal being drilled: low carbon steel and aluminium tolerate higher speeds, while stainless steel and hardened alloys require lower speeds and continuous cooling. Store bits in a dry place and replace blunt or chipped bits to maintain hole quality and operator safety.
