Steelmax Annular Cutters

Steelmax offers a full line of high-quality High Speed Steel (HSS) and Tungsten Carbide Tipped (TCT) annular cutters for all of your hole-making needs. We stock a full range of both HSS and TCT cutters from 7/16″ to 3″ in diameter and 1″, 2″ and 3″ depths of cut.   Custom sizes are also available.  All Steelmax annular cutters have standard Weldon shanks (3/4″ shank for cutter diameters up to 2-3/8″ and 1-1/4″ shank for cutter diameters above 2-3/8″).  As a result, Steelmax cutters will fit and improve the performance of any mag drill!

All Steelmax cutters ship with a pilot pin installed at no extra charge.

Annular cutters have many advantages over traditional twist drills:

  • Eliminates costly and time consuming step-drilling
  • Significantly less drilling time – 3-4 times faster than twist drills
  • Longer tool life – 5-10 times as many holes as a comparable twist drill bit
  • More accurate and higher quality holes – burr-free with no clean up
  • Easily drill on curved surfaces such as pipe or tubing
  • Create overlapping holes
  • Lower machine and horsepower requirements when compared to twist drills

Steelmax HSS cutters utilize an M2Al (aluminum additive) formulation which increases cutter life due to better heat propagation characteristics and its less brittle character compared to other M2 formulations, such as those using a cobalt additive.  HSS cutters are most cost effective for mild steel applications and holes up to 2-3/8″ in diameter in material up to 2″ thick and can be re-sharpened to extend cutter life.

Steelmax TCT cutters are made with the highest quality carbide available and are extremely well suited to work on harder materials and higher speed applications. TCT cutters are most cost effective for larger holes (over 1-1/2″ in diameter) and in thicker materials (2″ and over).

Steelmax High Performance Cutting Fluid should be used with all annular cutters for optimal cutting performance and to extend cutter life.  Our High Performance Cutting Fluid is a water-based cutting fluid that is bio-degradable and does not require time-consuming cleanup prior to welding or assembling parts.
