Annular Cutters

Types of Annular Cutting Products We Offer

An annular cutter is a specialized bit for drilling through steel that only cuts the outside of a hole. The cutter shreds the hole's perimeter into tiny chips as it rotates. After cutting through the perimeter, the round chunk of steel in the center of the cut falls out.
 

While some manufacturers typically design annular cutters for magnetic-based and core drills, they also work great in mills and can even function on many stationary drill presses. Choosing the appropriate annular cutter depends on the diameter of the hole you need, the depth of the cut and the type of material. We offer a broad range of annular cutters in multiple sizes to cut through various types of materials, including:

• Carbon steel.
• Stainless steel.
• Structural steel.
• Aluminum.
• Hard alloys.

When selecting a specific cutter, the primary factors you need to consider are the depth of the cut and the diameter.  Angles on the cutting teeth make a significant difference in how your tools perform. More precise angles enhance the cutter's life and efficiency.

In addition to our extensive inventory of cutters, we offer a range of pilot and ejector pins. These pins allow you to accurately locate the tool's position before the cutting begins and push the core out when the cutting finishes. Pilot pins also deliver a precise amount of oil to the cutting bit for lubrication.

We also sell entire multiple-piece cutter sets from trusted brands like Fein and Milwaukee®.

Advantages of Using Annular Cutters Over Conventional Drill Bits

Annular cutters offer superior hole-making capabilities compared to conventional twist drill bits. Some advantages of using annular cutters include:

• Minimal effort: An annular cutter uses multiple edges to cut with less effort and horsepower than traditional twist drills.
• Less material to cut: Twist drills cut away the entire hole. In contrast, annular cutters are hollow and cut only the perimeter of a hole. That means you'll need less time to cut, increasing your operation's efficiency.
• Lower costs: Since annular cutters can cut significantly more holes than twist drill bits, their replacement frequencies are far less. Their teeth also stay sharp longer, resulting in more cost savings for you.
• No step-drilling: When drilling metal, many twist bits require step-drilling a series of holes to get the diameter and depth you need. Annular cutters allow you to cut your required diameter and depth in one shot.
• Higher accuracy: Annular cutters are much more accurate than conventional bits because of the increased number of teeth and their degree of sharpness.
• Improved quality: Annular cutters produce smooth, burr-free holes resulting in less scrap and material waste.
