Drill bit for metal Proline 18.5 mm HSS DIN338 (short ground)

Proline Drill bit for metal 18.5 mm HSS DIN338 (short ground) is a high-speed steel cutting tool engineered for drilling precise holes in steel and a variety of other metals. Manufactured to the DIN 338 standard with a short ground (short/spot-length) geometry, this bit is suitable for both handheld drills and drill presses. The short ground design reduces overhang and improves rigidity, providing stable cutting performance when working on construction, metalworking and maintenance tasks that demand durable HSS tooling.

Advantages

The HSS material ensures good wear resistance and heat tolerance during continuous drilling operations, while the DIN 338 geometry delivers reliable cutting angles and chip removal. The short ground length increases stiffness, minimizing chatter and deflection for more accurate hole positioning. The bit is compatible with a wide range of metalworking applications and offers consistent hole quality when used with appropriate speeds and lubrication.

Suitable for

• Drilling holes in mild and alloy steels
• Spot drilling and pilot holes in sheet metal and plates
• Use with handheld electric drills and drill presses
• Maintenance, repair and construction metalwork

Key specifications

• Diameter: 18.5 mm
• Material: High-Speed Steel (HSS)
• Geometry: DIN 338 short ground (short/spot-length)
• Intended use: Drilling into steel and other metals
• Tool type: Twist drill bit for metal

How to use

Secure the drill bit firmly in the chuck of a handheld drill or drill press and ensure proper runout and alignment before starting. Select an appropriate drill speed for the material being drilled—lower speeds for harder steels—and apply steady, even pressure. Use cutting fluid or lubricant when drilling steel to reduce heat and extend tool life. Withdraw the bit periodically to clear chips when drilling deep holes. After use, clean the bit and store it dry to prevent corrosion.

Usage recommendations

For best results, match drilling speed and feed to the metal grade and thickness, use cutting fluid for continuous or heavy-duty work, and minimize overhang by using the short ground geometry as intended for improved rigidity and accuracy.
