Twist Drill — Metal Twist Drill, 12 mm, 135° Point Angle, Long (DIN 340), Bright Finished, Fully Ground, HSS-G

A Twist Drill long HSS‑G drill for deep metal holes, optimised for drilling machines and workshop applications.

• Long HSS‑G design for deep hole drilling
• 12 mm Diameter for precise, centred holes
• 135° Point Angle for harder materials and stainless steel
• Fully Ground Shank for high runout accuracy
• Bright Finished surface for improved handling and corrosion protection

Durable HSS‑G construction for efficient metalworking

The Twist Drill is manufactured from HSS‑G, a high‑speed steel with CNC grinding that creates very sharp cutting edges and excellent concentricity. This construction allows up to 40% faster drilling and requires about 50% less thrust force compared with conventionally formed HSS drills, which translates into less operator fatigue and more efficient machining. For customers working with steels, cast materials and harder non‑ferrous alloys, this combination significantly improves cycle times while maintaining hole quality.

Designed for deep holes and hard materials

Built to the DIN 340 long specification, the drill’s extended spiral length (Spiral Length 121 mm) and overall length (184 mm) make it particularly suitable when drill access is restricted or when deeper bores are required. The 135° point angle reduces initial biting on tough materials like stainless steel and cast iron, improving centring and reducing the tendency to wander. Use with an appropriate drilling machine and the correct speeds to exploit the long geometry for clean, precise bores.

Precision geometry and finish for clean results

The fully ground flute geometry and fully ground shank produce a high degree of runout accuracy, ensuring straighter holes and a better surface finish. The bright finished surface helps with chip evacuation and handling. These design elements are especially beneficial in professional workshops where repeatability and tool life are critical. Note that ground HSS drills can be more brittle than rolled types, so stable clamping and coolant are recommended for demanding tasks.

Practical tips for use, maintenance and support

For optimal performance, operate the drill at speeds and feeds matched to the material, and use coolant when machining harder steels to avoid overheating and premature wear. The ground geometry makes re‑grinding possible, but take care—grinding among professionals preserves the correct point angle and helix for continued precision.
