Overview

In metalworking, starting holes with perfect alignment is essential. The Accusize 5-piece ANSI M42 center drill set is designed to deliver crisp, precise centers across drills, lathes, and milling machines. Crafted from M42 high-speed steel with 8% cobalt, these drills balance sharpness and heat resistance to sustain performance through demanding jobs without excessive wear.

The center drills are single-fluted and ground from solid for consistent centering and smooth initial drilling. A 60° countersink angle ensures compatibility with standard machine centers, helping you begin precision holes with confidence rather than guesswork.

What’s included

  • No.1: 1/8" diameter x 3/64" web; 1-1/4" OAL
  • No.2: 3/16" diameter x 5/64" web; 1-7/8" OAL
  • No.3: 1/4" diameter x 7/64" web; 2" OAL
  • No.4: 5/16" diameter x 1/8" web; 2-1/8" OAL
  • No.5: 7/16" diameter x 3/16" web; 2-3/4" OAL

The set ships in a sturdy plastic box, keeping tools organized and protected from nicks while you move between stations or projects.

Material and design details

  • M42 HSS with 8% cobalt for better heat resistance and wear durability
  • Single-fluted, ground-from-solid construction for precise centering and smooth drilling
  • 60° standard countersink angle compatible with most machine centers

Practical use and benefits

These center drills help establish reliable center holes that guide subsequent operations. They’re suitable for preparing workpieces for turning between centers, and for starting holes before drilling or milling with accuracy. Visual feedback from the sharp edges and clean finishes can make setup faster and more predictable, especially on multi-step projects.

Storage and care: The included plastic case helps minimize handling damage and keeps your sizes visible at a glance, supporting an organized workshop routine. While results depend on context, the cobalt-enhanced steel and precise geometry are designed to maintain edge life under typical workshop conditions.
