Elevate your workshop capabilities with a tool designed for superior performance and exceptional longevity.This is a high-performance ground standard twist drill made from heavy-duty high speed steel. The fully ground twist drill has a precise concentricity. Thanks to the split point, this drill has good centring properties and requires little pressure. The meticulous manufacturing process guarantees that each hole is drilled with exacting accuracy, adhering to a strict h8 tolerance for perfectly sized results every time.The standout feature is the Shape C split point grinding at the tip. This advanced design allows the drill bit to engage the material immediately upon contact, eliminating the frustrating walking or skidding common with standard points. This self-centring action ensures pinpoint accuracy from the very start and significantly reduces the axial pressure needed to penetrate the workpiece. The result is a faster, more controlled, and less fatiguing drilling experience, even on smooth or curved surfaces. The 118° point angle, combined with a 20°-30° spiral angle, provides an optimal balance of aggressive cutting and efficient chip evacuation for clean, consistent performance.Designed for robust versatility, this 12.3 mm drill bit set is your go-to choice for a variety of materials. Its main application is drilling into tough materials like steel with a tensile strength up to 900 N/mm², as well as aluminium, brass, and plastics. It also demonstrates reliable performance in other materials, including bronze and cast iron, making it an indispensable and versatile asset for any electric tool accessory collection. The cylindrical shank ensures universal compatibility with standard drill chucks, providing a secure and stable fit.---Technical Specifications:* Net weight: 92 g* Diameter: 12.3 mm* Length: 151.0 mm* Spiral length: 101.0 mm* Tip grinding: Shape C: Split point* Tolerance: h8* DIN: 338* Material: HSS* Cutting direction: Right cutting* Shaft: Cylindrical* Drilling depth: 5 x diameter* Point angle: 118°* Spiral angle: 20° - 30°* Groove profile: Normal* Core: NormalMain Application:* Steel < 900 N/mm²* Aluminium* Brass* PlasticsOther Application:* Bronze* Cast iron. tradeinn Bricoinn
