Product Description
The CMT Forstner Bit 35mm with 10mm Shank (RH) is a precision-engineered boring bit crafted from super strength SP steel, designed to drill clean, flat-bottom holes in softwood with exceptional accuracy. Purpose-built for cabinetmakers, woodworkers, and furniture builders, this 35mm bit excels at hinge installation, shelf pin boring, and the creation of arched or oval openings at any angle - giving you repeatable, splinter-free results in a wide range of wood construction and finishing tasks.
Key Features
- Super Strength SP Steel Construction - delivers long-lasting cutting performance, meaning fewer bit replacements and consistent results across extended use in softwood drilling applications.
- 2 Precision-Ground Cutting Edges - score and shear the wood fiber cleanly so that bore walls stay smooth and chip-free, reducing sanding and cleanup time after drilling.
- 2 Ground Spurs (V2) - score the perimeter of the hole ahead of the main cutting edges, producing a clean, defined bore wall that is ideal for visible cabinetry and furniture work.
- 35mm Diameter - the standard size for European-style concealed cabinet hinges, making this bit a go-to tool for kitchen cabinet and furniture hardware installation.
- 10x30mm Shank - provides a secure grip in drill press chucks and handheld drills, reducing wobble and maintaining on-center accuracy during plunge cuts.
- Right-Hand (RH) Rotation - matches standard drill press and handheld drill operation so you can use this bit without special setup or reversal of chuck direction.
- Flat-Bottom Hole Geometry - produces a precisely flat base at the bottom of each bore, which is essential for correct seating of concealed hinges, brackets, and hardware mounting plates.
- Suitable for Angled Drilling - the balanced design allows drilling at any angle to create oval and arched openings, expanding the range of joinery and decorative applications beyond simple plunge drilling.
Why This Product
- Engineered for Concealed Hinge Installation - the 35mm diameter is the recognized standard for European cabinet hinge cups, so this bit fits directly into the workflow for kitchen, bath, and furniture cabinet assembly without adapters or workarounds.
- Long-Lasting SP Steel Means Lower Cost Per Hole - super strength steel holds a sharp edge longer than standard tool steel, so the bit stays productive through more cuts before resharpening is needed, lowering the per-hole cost over time.
- Versatile Beyond Simple Plunge Drilling - because the bit can be used at any angle, it is not limited to straight-through hinge bores. Use it to create niches, arched openings, and recesses for brackets, straps, frames, and grids in a single tool.
- Dual Spur Design for Clean Entry in Finished Work - the 2 ground spurs score the wood surface before the cutters engage, minimizing tearout on the face of finished panels and cabinet doors where appearance is critical.

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 supports long-lasting cutting performance in softwood applications.
Can this bit be used at an angle, or only for straight plunge drilling?
This bit is capable of drilling at any angle, which allows you to create oval and arched openings in addition to standard flat-bottom plunge holes. This makes it useful for decorative openings and recessed hardware installations beyond straightforward perpendicular boring.
What shank size does this bit use, and what tools can it be used with?
The bit has a 10x30mm shank, which fits a 10mm chuck. It is compatible with a drill press for precise, repeatable bores, and can also be used with a handheld drill when care is taken to maintain alignment and control plunge speed.
Why is the 35mm size significant for cabinet and furniture work?
The 35mm diameter corresponds to the standard cup size used for European-style concealed cabinet hinges, which are widely used in kitchen cabinets, bathroom vanities, and furniture carcasses. Having a dedicated 35mm Forstner bit ensures the hinge cup seats correctly for proper door alignment and smooth operation.
