HSS Mortise Bits for Mortising Machines
HSS mortise bits provide a reliable cutting solution for machining slots, mortises and similar recesses in solid wood. Designed for use on mortising machines and compatible woodworking equipment, these tools combine traditional high-speed steel construction with 2- or 4-flute cutting geometry.
High-speed steel offers excellent toughness and can maintain a sharp cutting edge, making it particularly suitable for machining natural wood where clean cutting and edge sharpness are important.
2-Flute & 4-Flute Options
GDP Tooling offers these HSS mortise bits in 2-flute and 4-flute configurations to accommodate different machining requirements.
The appropriate flute configuration depends on the machine, mortise dimensions, material and operating parameters. Proper chip evacuation is particularly important when machining deeper slots and mortises.
Multiple Shank Sizes
Standard shank configurations include:
10 mm shank
13 mm shank
1/2″ shank
This range allows the appropriate tool to be matched to a variety of mortising machines and spindle configurations.
A selection of standard diameters is available, with certain sizes stocked for quick delivery. For applications requiring a non-standard diameter, custom HSS mortise bits can be manufactured with a minimum order quantity of 10 pieces.
For best results, select the cutting diameter, flute configuration and shank size according to the machine and mortising application.
