Twist drill bit Bosch Metal HSS-G DIN 340 5 mm

Twist drill bit Bosch Metal HSS-G DIN 340 5 mm is a high-speed steel (HSS) right-hand cutting drill designed for precise metalworking. It features a 135° split-point tip manufactured to DIN 1412 C and a diameter tolerance of h8. The bit is ground from solid metal, has two flutes for efficient chip evacuation and an oxide-coated surface to improve chip removal. The shank diameter equals the drill diameter; finish is polished for single-pack items and black for five-packs.

Advantages

The HSS-G construction provides increased wear resistance and long life when drilling metal. The 135° split point reduces walking at the drill start and improves centring without the need for a pilot hole. Oxide coating and ground flutes enhance chip flow and reduce clogging, while the cylindrical shank with diameter-equal design ensures stable clamping in standard chucks.

Suitable for

• Drilling holes in mild and alloyed steels
• General metal fabrication and maintenance work
• Use with handheld drills and drill presses
• Professional and DIY metalworking tasks requiring a 5 mm hole

How to use

Mark and, if necessary, centre-punch the drilling position to improve accuracy. Secure the workpiece and select a suitable cutting speed and feed for the material being drilled. Use cutting lubricant or coolant when drilling steel to extend tool life and improve chip evacuation. Clamp the cylindrical shank in a standard drill chuck, align the drill, and start at low speed to establish the hole, then increase speed as appropriate.

Usage recommendations

For best results when drilling steel, apply cutting oil and maintain moderate feed pressure; avoid excessive heat build-up by using intermittent drilling or coolant. Replace the bit when wear or chipping at the 135° split point degrades performance.
