Annular Cutter JESTUOUS 7/8″ 3/4″ Weldon Shank HSS Slugger Bit

Description

Product Overview

The JESTUOUS annular cutter is engineered for professionals who demand precision and durability in metalworking applications. Constructed from high‑speed steel (HSS), the cutter offers exceptional hardness and heat resistance, allowing it to maintain a sharp cutting edge even under demanding conditions. Its 3/4 inch weldon shank provides a secure, rigid connection to magnetic drill presses, mills, and large drill presses, ensuring consistent torque transfer and reducing vibration during operation.

Designed with a 7/8 inch cutting diameter, this slugger‑type bit creates clean, burr‑free holes in a variety of conductive materials, including carbon steel, stainless steel, aluminum, brass, and cast iron. The included pilot pin, measuring 6.34 × 77 mm, initiates the cutting process with minimal effort, reducing start‑up time and preventing misalignment. The cutter’s geometry features multiple cutting edges that distribute load evenly, resulting in smoother cuts, reduced material waste, and extended tool life. With a cutting depth of 1 inch, it is suitable for a wide range of thicknesses, making it a versatile addition to any industrial toolkit.

Usage

When used with a magnetic drill press, the JESTUOUS annular cutter excels in creating precise holes for bolt holes, conduit passages, and mounting points in structural steelwork. Its compatibility with most major brands of magnetic drills means you can quickly integrate it into existing setups without the need for additional adapters. For milling applications, the cutter can be mounted in standard tool holders, allowing it to perform on CNC machines and conventional mills with equal efficiency.

To achieve optimal results, ensure the workpiece is securely clamped and the drill speed is set according to the material being cut—typically between 500 and 1500 RPM for steel and higher speeds for softer metals. Apply cutting fluid or lubricant to reduce heat buildup and extend the cutter’s lifespan. After each use, clean the cutter of debris and inspect the cutting edges; if necessary, re‑sharpen the HSS blades to restore performance. The pilot pin should be stored in its plastic case when not in use to protect its tip from damage.

FAQ

What materials can this annular cutter handle?

The cutter is suitable for a wide range of metals, including carbon steel, stainless steel, aluminum, brass, cast iron, and lower‑BHN stainless steel. Its HSS blades maintain sharpness across these materials, delivering clean holes with minimal burrs.

Can the cutter be re‑sharpened?

Yes. One of the key advantages of the high‑speed steel construction is the ability to re‑sharpen the cutting edges. This extends the cutter’s service life and provides a cost‑effective solution for repeated use.

Is the cutter compatible with all magnetic drill brands?

The cutter’s 3/4 inch weldon shank is a standard size that fits most major magnetic drill brands. It can also be used with conventional mills and large drill presses when equipped with appropriate tool holders.

How do I maintain optimal performance?

Maintain performance by using appropriate cutting speeds, applying cutting fluid, and regularly cleaning the cutter after use. Inspect the cutting edges for wear and re‑sharpen when necessary. Store the pilot pin in its plastic case to protect the tip.
