Annular Cutter Set 13 Pcs by S&F STEAD & FAST, Cutting Depth 1″ Cutting Diameter 7/16″ to 1-1/16″ Inch, Mag Drill Bits Kit for Magnetic Drill Press, with 2 Pilot Pins

Description

Product Overview

The Annular Cutter Set by S F Stead Fast is engineered for demanding metalworking environments where precision, durability, and efficiency are paramount. Each of the 13 cutters is forged from M2AL high speed steel, a premium alloy known for its exceptional wear resistance and ability to maintain a sharp cutting edge even under high temperature conditions. The cutters cover a comprehensive size range from 7/16″ to 1-1/16″ outside diameter, providing flexibility for a wide variety of hole sizes while maintaining a consistent 1″ cutting depth. The CNC‑machined 3/4″ Weldon shank with dual flats offers a secure, vibration‑free connection to magnetic drill presses, ensuring the cutter remains stable throughout the drilling process. The set also includes two pilot pins that guide the cutter into the workpiece, reducing the risk of misalignment and delivering burr‑free, reamed holes with a smooth finish.

All components are packaged in a rugged, molded case that protects the cutters during transport and storage. The case also holds a bonus hex wrench, allowing users to quickly adjust the cutter shank without the need for additional tools. Detailed usage instructions are printed on the interior of the case, providing clear guidance on optimal feed rates, clamping techniques, and safety precautions. This comprehensive approach minimizes setup time and maximizes productivity on the shop floor.

Technical specifications include a product dimension of 8.27 x 3.15 x 8.07 inches and a weight of 3.15 pounds, making the kit portable yet robust enough for industrial use. The cutters are compatible with a broad range of magnetic drill brands, such as Alfra, BDS, Dewalt, Euroboor, Hougen, and Ruko, ensuring seamless integration into existing equipment inventories.

Usage

This cutter set is ideal for fabricators, maintenance technicians, and production engineers who require clean, precise holes in steel, stainless steel, and other hard metals. The cutters excel in applications such as creating bolt holes, mounting brackets, and conduit passages where a smooth, reamed finish is essential to prevent stress concentrations. Because the cutters are designed for single‑layer drilling, they are best suited for workpieces thicker than 1/2″; for thinner material, a supporting steel sheet should be placed beneath the workpiece to ensure adequate magnetic grip.

When using the set, it is crucial to maintain a low feed rate during the initial engagement of the cutter with the material, especially for the smaller diameters. Once the cutter has penetrated 2‑3 mm, the feed rate can be increased to the manufacturer’s recommended level to optimize cutting speed without compromising cutter life. Proper clamping of the workpiece is essential; a secure magnetic hold prevents movement that could lead to uneven holes or premature cutter wear.

The set can also be adapted for use on drill presses with the addition of a compatible annular cutter arbor, expanding its versatility beyond magnetic drilling stations. This adaptability makes the kit a valuable investment for workshops that employ both portable magnetic drills and stationary drill presses.

FAQ

What material are the cutters made from?

The cutters are forged from M2AL high‑speed steel, which offers excellent hardness, wear resistance, and the ability to retain a sharp edge at high cutting temperatures.

Can these cutters be used on a standard drill press?

Yes, the cutters can be used on a drill press when paired with a compatible annular cutter arbor. This expands their applicability beyond magnetic drill stations.

What is the recommended feed rate for the smallest cutter?

Start with a low feed rate to engage the cutter gently, especially for diameters 7/16″ and 1/2″. Once the cutter has entered the material 2‑3 mm, increase to the manufacturer’s recommended rate to improve efficiency while protecting the cutter.

Is the set suitable for drilling multiple layers of material?

No. This series is designed for single‑layer drilling only. For multi‑layer applications, a different cutter type should be selected to avoid excessive wear and potential damage.

What should I do if the workpiece is thinner than 1/2″?

Place a 3/8″ steel sheet beneath the thin workpiece to provide sufficient magnetic grip for the drill. This prevents movement and ensures a stable drilling environment.
