Product Description
CMT Forstner Bit 24mm (8mm Shank, Right-Hand) by CMT is a precision boring tool engineered for drilling clean, flat-bottom holes in softwood. Built from super strength SP steel, this 24mm bit delivers long-lasting cutting performance for woodworking tasks ranging from hinge installation and shelf pin drilling to creating arched openings, oval cutouts, and niches for brackets, straps, frames, and grids - all at any angle. Whether you are working at a drill press or with a handheld drill, this right-hand rotation Forstner bit produces accurate, repeatable results with minimal tearout.
Key Features
- Super Strength SP Steel Construction - the SP steel material provides long-lasting cutting performance, reducing the frequency of bit replacement and keeping cuts consistent over time.
- 2 Precision Ground Spurs - dual spurs score the wood fiber ahead of the main cutting edges, producing clean bore walls free of splintering or tearout on softwood surfaces.
- 2 Cutting Edges - two cutting teeth work in tandem to evacuate material efficiently and deliver a smooth, flat bottom in every hole.
- 24mm Boring Diameter - a 24mm cutting diameter is well-suited for European hinge cups, shelf pin holes, and similarly sized hardware cutouts common in cabinet and furniture work.
- 8x30mm Shank - the 8mm shank provides a secure grip in compatible drill chucks, reducing slippage and maintaining concentricity during the cut.
- Right-Hand Rotation - standard RH rotation is compatible with virtually all drill presses and handheld drills, making this bit straightforward to use without any special tooling.
- Flat-Bottom Hole Geometry - Forstner-style geometry produces a flat-bottomed bore rather than a tapered point, which is essential for hinge mortising, hardware pockets, and decorative arched or oval openings.
- Compact 3-35/64" Overall Length - a total length of 3-35/64 in. keeps the bit manageable in both drill press and handheld applications without sacrificing reach for standard workpiece thicknesses.
Why This Product
- Purpose-built for flat-bottom boring - unlike twist or brad-point bits that leave a tapered cavity, this Forstner bit cuts a true flat-bottom hole, making it the correct choice for hinge cup installation, hardware pockets, and recessed niches where full depth matters.
- Versatile angle and overlap capability - Forstner bits can drill overlapping holes and bore at any angle, enabling curved or arched openings and decorative profiles that standard bits cannot achieve.
- SP steel for extended service life - the super strength steel construction is designed for long-lasting cutting performance, meaning the bit holds its edge longer on repetitive softwood drilling tasks.
- Standardized 8mm shank for broad compatibility - the 8x30mm shank fits a wide range of drill press chucks and handheld drill chucks, so there is no need for adapters or specialty tooling to get started.

Frequently Asked Questions
What material is this Forstner bit designed to cut?
This bit is designed for drilling precise flat-bottom holes in softwood. The super strength SP steel construction provides long-lasting cutting performance suited to softwood boring applications.
Can this bit drill holes at an angle or create overlapping bores?
Yes. Forstner-style geometry allows the bit to bore holes at any angle and to create overlapping cutouts, which makes it suitable for arched openings, oval profiles, and angled hardware pockets that standard twist or brad-point bits cannot produce.
What shank size does this bit use, and will it fit my drill?
This bit features an 8x30mm shank. It is compatible with drill press chucks and handheld drill chucks that accept an 8mm shank. The right-hand rotation is standard, so no special setup is required.
How many cutting edges and spurs does this Forstner bit have?
The bit has 2 cutting teeth and 2 precision ground spurs. The spurs score the wood fiber ahead of the cutting edges, which helps produce clean hole walls and a smooth, flat bottom with minimal tearout.
