## Long description

Set of 19 GRAPHITE Pro-Tec HSS-CNC metal drill bits with 124° point angle, covering diameters from 1.0 to 10.0 mm. These drill bits are manufactured from high-speed steel (HSS) and designed for machining metal on both CNC machines and with hand drills. The set includes standard incremental sizes commonly used in metalworking, maintenance and fabrication tasks, providing precise hole cutting in steel and non-ferrous alloys.
Advantages
The HSS material offers good hardness and heat resistance for drilling through various metals. A 124° split-point geometry reduces walking at contact and improves centering without the need for a pilot hole on many materials. The set format covers a wide range of diameters, allowing selection of the correct size for different applications and reducing time spent changing bits. The uniform shank design fits most standard chucks and supports stable clamping during operation.
Suitable for
Drilling holes in mild and hardened steel (with appropriate cutting speed and coolant)
Working on non-ferrous alloys such as aluminum and brass
CNC machining centres and manual drill presses
On-site maintenance, repair and fabrication tasks
Key specifications

Quantity: 19 pieces covering standard increments
Shank: straight cylindrical shank suitable for standard chucks
How to use
Select the appropriate drill diameter for the hole required and secure the workpiece to prevent movement. Install the drill bit in a properly tightened chuck, set the drilling speed according to material hardness, and use steady feed pressure. For steel and other hard materials, apply cutting fluid or coolant to reduce heat and extend tool life. Retract periodically on deep holes to clear chips and inspect the bit for wear.
Usage recommendations
For best results, start with lower spindle speeds and gradually increase as needed, and use cutting fluid when drilling steels. Match drill speed and feed to the workpiece material: higher speeds for softer non-ferrous metals and lower speeds for hardened steels. Replace worn bits to maintain hole quality and avoid excessive force that can cause breakage.
