Description
Product Overview
The OSCARBIDE 1-1/8″ x1 annular cutter is engineered to meet the demanding requirements of modern metalworking and fabrication environments. Constructed from high‑grade tungsten carbide, the cutter delivers exceptional hardness and wear resistance, allowing it to maintain a sharp cutting edge even after thousands of penetrations. The 3/4″ Weldon shank provides a secure, rigid connection to magnetic drill presses, reducing wobble and ensuring consistent hole placement. Integrated directly into the cutter is a precision‑machined pilot pin measuring 6.34 × 0.77 mm, which guides the tool into the workpiece and eliminates the need for a separate center drill, saving valuable setup time.
Designed with a thin‑walled, dual‑alternating‑tooth geometry, the cutter removes material efficiently while generating minimal heat, which helps preserve the integrity of both the tool and the workpiece. The cutter’s cutting diameter of 1‑1/8″ and a depth of cut of 1 inch make it ideal for creating large‑diameter holes in a variety of materials, including ferrous and non‑ferrous metals, cast iron, stainless steel, aluminum, copper, and even engineered plastics. The robust construction also enables use on pipe and plate stock, providing versatility across a wide range of industrial applications.
Usage
When paired with a magnetic drill press, this annular cutter excels in high‑speed drilling operations where precision and surface finish are critical. It is particularly well‑suited for tasks such as creating conduit openings in electrical panels, fabricating mounting holes in heavy‑duty equipment, and preparing large‑diameter passages for fluid or gas piping. The cutter’s ability to produce burr‑free holes reduces the need for secondary deburring processes, which can save both labor and material costs.
Because the cutter is compatible with standard magnetic drill chucks and can be easily mounted on conventional drill presses, it offers flexibility for both on‑site field work and shop‑floor production. Its pilot pin ensures accurate entry into the workpiece, making it an excellent choice for operators who require repeatable hole locations without the added step of pre‑drilling a center hole. The cutter’s design also accommodates a range of cutting fluids, allowing users to employ coolant or lubricant to further extend tool life and improve chip evacuation.

FAQ
What materials can this annular cutter handle?
The cutter is suitable for a wide range of materials, including steel, stainless steel, cast iron, aluminum, copper, brass, engineered plastics, and wood when used with appropriate cutting speeds and lubricants.
Can the cutter be re‑sharpened?
Yes, the carbide cutting edge can be re‑sharpened by a qualified tool‑reconditioning service, extending the cutter’s usable life and maintaining optimal performance.
What size pilot pin does the cutter use?
The built‑in pilot pin measures 6.34 mm in diameter by 0.77 mm in length, providing precise guidance for hole entry without the need for a separate center drill.
Is this cutter compatible with standard magnetic drill chucks?
Absolutely. The 3/4″ Weldon shank is designed to fit standard magnetic drill chucks and can also be used on conventional drill presses with compatible tool holders.
What is the recommended cutting speed for aluminum?
For aluminum, a cutting speed of 150–200 surface feet per minute (SFM) is recommended, using a suitable cutting fluid to improve chip evacuation and reduce heat buildup.
