27000 Series TCT (Carbide) Annular Cutter

27000 Series TCT Annular Cutter — Maximum Performance in Hard Metals

The 27000 Series Tungsten Carbide Tipped (TCT) annular cutters are purpose-built for drilling through the most demanding metals encountered on industrial and structural job sites. Specially engineered for alloys, high tensile steels, and stainless steel, these cutters deliver cutting performance where standard high-speed steel tooling falls short. Each cutter ships with a pilot pin included and is fitted with a universal shank for broad machine compatibility. Available individually or in kits, the 27000 Series suits contractors who need reliable, repeatable hole quality in tough material applications.

Technical Specifications

Unlike standard HSS annular cutters, the TCT construction of the 27000 Series makes it the appropriate choice when working with hardened or abrasion-resistant steels that would rapidly dull conventional tooling. The universal shank design means these cutters integrate directly with a wide range of magnetic drill platforms without requiring adapters, reducing downtime on site.

Key Features & Benefits

Tungsten Carbide Tips

Tungsten carbide is significantly harder and more wear-resistant than high-speed steel, allowing the cutter to maintain a sharp cutting edge through extended use in tough metals. For contractors drilling stainless steel or hardened alloys regularly, this translates to fewer tool changes and more consistent hole quality over the life of the cutter.

Engineered for Tough Metals

The 27000 Series is specifically designed to handle alloys, high tensile steels, and stainless steel — materials that are common in structural, fabrication, and heavy industrial applications. Having a cutter rated for these materials means contractors can take on a broader range of work without sourcing specialty tooling for each job.

Universal Shank

The universal shank is compatible with the majority of magnetic drill presses used in the field, eliminating the need for proprietary adapters. This makes the 27000 Series a practical choice for contractors who operate multiple drill platforms or work across different job sites.

Pilot Pin Included

Each cutter comes with a pilot pin, which centers the cutter on the workpiece and prevents walking at the start of the cut. This is particularly important when drilling into hard or smooth metal surfaces where accurate hole placement is critical.

Wide Range of Depths and Diameters

With depth of cut options from 1" through 8" and diameters from 1/2" to 8", the 27000 Series covers a broad spectrum of hole sizes and material thicknesses. Contractors can select the exact cutter geometry required for each application rather than compromising with an approximate size.

Available as Individuals and in Kits

The option to purchase individual cutters or complete kits gives contractors flexibility in how they stock tooling. Kits are well-suited for outfitting a new crew or job site, while individual cutters allow targeted replacement of worn tooling without unnecessary expense.

Common Applications

Structural Steel Fabrication

Drilling clean, accurate holes in high tensile structural steel sections for bolted connections, gussets, and brackets where hole quality and dimensional accuracy are required.

Stainless Steel Work

Creating holes in stainless steel plate, tube, or sheet in applications such as food processing equipment, architectural metalwork, or marine fabrication where corrosion-resistant materials are specified.

Alloy Steel Components

Machining holes in hardened alloy steel parts used in heavy equipment, tooling, or industrial machinery where standard HSS cutters would wear prematurely.

On-Site Magnetic Drill Operations

Used with magnetic drill presses on structural steel beams, columns, and plates during steel erection or modification work, where portability and hole accuracy are both essential.
