Product Description
CMT Forstner Bit - 32mm Diameter, 10mm Shank, Right-Hand Rotation is a precision boring tool engineered in super strength SP steel for drilling clean, flat-bottom holes in softwood. Whether you are cutting seat pockets for shelf pins, mortising for European cup hinges, or shaping oval and arched openings at any angle, this 32mm bit delivers repeatable accuracy and long-lasting cutting performance across a wide range of woodworking tasks.
Key Features
- Super Strength SP Steel Construction - resists wear and maintains a sharp cutting edge through extended use, reducing the frequency of bit replacement and keeping operating costs low.
- 2 Precision-Ground Cutting Edges - paired cutting geometry scores and removes material evenly so flat-bottom holes come out level and consistent, with no need for secondary cleanup passes.
- 2 Ground Spurs (V2) - spurs sever wood grain ahead of the main cutters, producing crisp bore walls and chip-free entry surfaces even in figured or soft-grained softwood.
- Toothed Rim Design at 32mm - at this larger diameter the toothed rim prevents heat buildup during deep or prolonged cuts, protecting both the bit and the workpiece from heat-related damage.
- Right-Hand Rotation (RH) - compatible with standard drill presses and handheld drills, no adapter or reversed-spindle machine required.
- 10x30mm Shank - the generous 30mm grip length seats securely in the chuck and minimizes runout, contributing to the positional accuracy needed for hinge and hardware installations.
- Angled Entry Capability - the bit geometry allows boring at any angle, making it practical for creating niches, arched openings, and recesses for brackets, straps, frames, and grids.
Why This Product
- Reliable flat-bottom boring for hardware installation - hinge cups, shelf pins, and cabinet hardware require a precisely flat, clean bore floor. The SP steel construction and paired cutting edges deliver that result consistently without rework.
- Versatile beyond straight-down drilling - the ability to plunge at any angle means one bit handles not just vertical pocket holes but also arched openings and angled niches for frames, grids, and structural straps.
- Built to last in a production environment - super strength SP steel is specified for long-lasting cutting performance, making this bit a practical choice for shops that run repetitive boring cycles rather than occasional single-project use.
- Right-sized shank for standard equipment - the 10mm round shank fits the collets and chucks found on common drill presses and handheld drills, so no special tooling is needed to put this bit to work immediately.

Frequently Asked Questions
What material is this Forstner bit rated for?
The CMT 537.320.31 is designed for drilling in softwood. The super strength SP steel construction provides long-lasting cutting performance in these materials. For best results and longest bit life, use it within its rated material category.
Can this bit be used at an angle rather than drilling straight down?
Yes. The bit geometry is specifically suited for creating oval and arched openings at any angle, as well as cutting niches for the installation of brackets, straps, frames, and grids - not just standard vertical plunge cuts.
What shank size does this bit use, and will it fit a standard drill press chuck?
The bit uses a 10x30mm round shank. A 10mm shank fits securely in the chucks found on most drill presses and handheld drills without requiring any special adapter.
Why does a 32mm Forstner bit use a toothed rim instead of a smooth rim?
At larger diameters such as 32mm, more material is removed per revolution and heat can build up quickly during deep or sustained cuts. The toothed rim design on this bit helps prevent overheating, protecting both the cutting edge and the workpiece surface during longer boring operations.
