Industrial-Grade HSS 6542 (M2) Jobber Length Drill Bit — High-Performance Precision Drilling for Multi-Metal Applications

Overview

The HSS 6542 (M2) Jobber Length Drill Bit is the workhorse of industrial drilling. Forged from high-molybdenum High-Speed Steel (M2 Grade), this bit offers a superior balance of toughness, wear resistance, and red-hardness compared to standard HSS. Designed for high-speed automated processes and manual precision work, it is engineered to deliver clean, accurate holes across a wide variety of medium-to-hard metals, including alloy steels and cast iron.

Key Selling Points

  1. Premium HSS 6542 (M2) Composition: Infused with Tungsten, Molybdenum, and Vanadium, providing higher heat resistance and edge retention than conventional M1 or carbon steel bits.
  2. Precision Fully Ground Flutes: The bright ground flutes ensure rapid chip evacuation and reduced friction, minimizing heat buildup and preventing the bit from binding in deep-hole applications.
  3. 118° Split Point Geometry: The industry-standard tip angle provides a balanced cutting action with reduced thrust requirements. It ensures accurate starts and consistent performance on flat and curved surfaces.
  4. Jobber Length Versatility: The standard length-to-diameter ratio offers the perfect compromise between reach and rigidity, making it suitable for the widest range of industrial drilling tasks.
  5. Industrial Hardness (HRC 63-65): Heat-treated to professional-grade specifications to ensure long-term durability and the ability to cut through high-tensile materials without losing its edge.

Target Materials & Applications

  • Alloy Steels: Low-to-medium carbon steels and tool steels.
  • Cast Iron: Grey and ductile iron.
  • Non-Ferrous Metals: Aluminum alloys, copper, and brass.
  • General Purpose: Structural steel, plastics, and high-density composites.
