Hougen 12628 Annular Cutter 7/8 in Hss Tin Coated

Product Description

The HOUGEN 12628 is a high speed steel (HSS) annular cutter designed for clean, fast hole-cutting in metal. Ground from M2-grade HSS and finished with a titanium nitride (TiN) coating, it cuts a 7/8-inch diameter hole to a depth of 1 inch per pass. The Weldon flat shank with two flats indexes securely into compatible magnetic drill press chucks and arbors, preventing slippage under load. The TiN finish reduces friction, extends tool life, and helps the cutter shed heat during continuous cutting cycles. Machinists, ironworkers, structural steel fabricators, and field maintenance crews are the primary users of this cutter type.

The HOUGEN 12628 is suited for drilling through mild steel, stainless steel, and general steel stock in both shop and field environments. Its 3/4-inch Weldon shank is a standard connection size compatible with magnetic drill presses and milling setups configured for Weldon-style tooling. Typical applications include structural steel fabrication, beam drilling, plate work, and any task requiring a precise, burr-minimized hole without the material waste of a twist drill. The 1-inch depth of cut accommodates most standard structural steel sections in a single pass.

Key Features

• 7/8-inch cutter diameter with 1-inch depth of cut in a single pass
• M2 high speed steel construction for durability in ferrous metal cutting
• Titanium nitride (TiN) coating reduces friction and extends cutting life
• 3/4-inch Weldon flat shank with 2 flats for positive chuck engagement
• Compatible with mild steel, stainless steel, and general steel stock
• Compact 0.21-pound weight suitable for use in handheld magnetic drill presses

Compatibility

Designed for use with magnetic drill presses and milling machines equipped with a 3/4-inch Weldon flat shank arbor or chuck. Rated for cutting mild steel, stainless steel, and general steel materials.

Installation Notes

Installation is performed by machinists, ironworkers, or maintenance technicians familiar with magnetic drill press operation. Power down and de-energize the drill press before inserting or removing the cutter. Secure the shank fully into the arbor and tighten all set screws against both Weldon flats before operation. Use cutting fluid or lubricant appropriate for the workpiece material to extend tool life and maintain cut quality.
