Annular Cutter Set 11pc 2in Cutting Depth - Mag Drill Bit Kit

In this review of the annular cutter set, the bottom line is straightforward: this kit is for metalworkers and fabricators who need fast, precise deep-hole cutting without fuss. The 11pc set covers common diameters from 7/16' to 1-1/16' and delivers consistent, clean holes to a 2in depth, so it removes the need for multiple passes with twist bits. Built from hardened M2 HSS and fitted with a 3/4' Weldon shank, it is designed to work on magnetic drills and hold up to demanding steel, aluminum, and copper jobs.

Key Features

• Multi-cut geometry teeth: Provide faster penetration and cleaner holes, reducing the need for deburring after cutting.
• M2 HSS construction: Hardened to high hardness for long wear life and to withstand the side forces of annular cutting.
• 2in cutting depth: Allows through and partial-depth holes in thick plate and structural material without stepping up cutters.
• 3/4' Weldon shank: Ensures compatibility with most major magnetic drill brands and secure mounting under load.
• Spiral flute design: Ejects chips efficiently to minimize clogging and maintain smooth cutting progress.
• Custom carrying case and pilot pins: Keeps the 11 sizes and two pilot pins organized and provides accurate hole centering.

Who It's For

This kit suits fabricators, maintenance technicians, and shop owners who frequently drill holes in steel, aluminum, and copper up to 2in deep and want a complete range of common diameters in one case. It is especially useful where a magnetic drill is used and fast, repeatable holemaking is required on plate, beam flanges, and brackets.

It is less suited to occasional home users who only need single holes or to applications requiring holes smaller than 7/16' or deeper than 2in; those users may find a smaller set or specialized cutters a better fit.

Pros & Cons

Pros

• Comprehensive size range from 7/16' to 1-1/16' covers most common jobs without buying extras.
• Tough M2 HSS build and hardened cutting edges extend life under heavy use.
• 3/4' Weldon shank and spiral flutes combine secure mounting with effective chip evacuation.

Cons

• Cutting depth is limited to 2in, so it will not replace longer annular cutters for very deep holes.
• The set is geared to standard mag-drill use and may be overkill for infrequent, light-duty drilling.

Specifications

Our Verdict

The ZELCAN 11pc annular cutter set is a practical, value-minded kit for professionals and frequent users who need reliable 2in-deep holes in steel, aluminum, and copper. Its hardened M2 HSS cutters, Weldon shank compatibility, and complete size range make it a solid choice for shop and field work, though users needing deeper holes should select longer cutters.

Frequently Asked Questions

Will these fit my magnetic drill?
They use a 3/4' Weldon shank, which fits most major magnetic drill models that accept that shank standard.

Can they cut stainless steel?
The cutters are M2 HSS hardened for steel cutting; they will cut stainless but expect slower feeds and proper coolant for best life.

Are pilot pins included?
Yes, two pilot pins are supplied to aid alignment and accurate hole starts.
