Hougen 11111 Annular Cutter 27/64 in Hss Bright

Product Description

The HOUGEN 11111 is a high speed steel annular cutter designed for clean, precise hole cutting in metal fabrication and structural steel work. With a cutter diameter of 0.4219 inches (27/64 inches) and a cutting depth of 1/4 inch, this cutter removes only a core plug rather than reducing the full hole to chips, reducing heat buildup and extending tool life. The M2 high speed steel construction and bright uncoated finish make it a solid choice for general-purpose drilling in mild steel, stainless steel, and hardened steel. The 3/8 inch shank provides secure tool holding in compatible magnetic drill presses and arbors.

This annular cutter is suited for metalworking trades including ironworkers, structural steel fabricators, pipefitters, and maintenance mechanics. It is a practical option for production drilling tasks where hole quality and speed matter. The 27/64 inch diameter is commonly used for clearance holes, tapping operations, and bolt hole preparation in light to medium plate work.

Key Features

Compatibility

Designed for use in magnetic drill presses and drilling arbors that accept a 3/8 inch shank annular cutter. Compatible material applications include mild steel, stainless steel, and hardened steel as specified by the manufacturer.

Installation Notes

Annular cutters should be installed and changed by a qualified metalworking tradesperson or machinist. Always power down and lock out the drill press or magnetic drill unit before changing cutters. Ensure the shank is fully seated and secured in the arbor before operation, and use cutting fluid appropriate for the workpiece material to reduce heat and extend cutter life.
