CMT Forstner Bit - 14mm Diameter, 8mm 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 installing cabinet hinges, mounting shelf pins, or routing out niches for brackets and hardware straps, this 14mm bit delivers repeatable accuracy with two precision-ground cutting edges and two scored spurs that produce chip-free bore walls. The right-hand rotation and 8x30mm shank make it compatible with both drill presses and handheld drills, giving woodworkers a versatile flat-bottom boring solution for joinery, cabinetry, and framing applications.

Key Features

• Super Strength SP Steel Construction - long-lasting cutting performance means fewer resharpening cycles and more consistent results across extended production runs in softwood.
• 2 Precision-Ground Cutting Edges - two cutting teeth shear material cleanly at the bottom of the bore, producing a flat, smooth floor that is ready for hardware seating without additional cleanup.
• 2 Ground Spurs - the paired spurs score the wood fiber ahead of the main cutting edges, preventing tear-out at the rim of the hole and leaving a crisp, clean opening wall.
• 14mm Cutting Diameter - sized for common hinge cup, bracket, and hardware hardware recesses, eliminating the need for step-drilling or secondary sizing passes.
• 8x30mm Shank - the 8mm shank seats securely in standard drill press chucks and handheld drill chucks, reducing wobble and keeping the center point on target during plunge.
• Right-Hand Rotation - works with the standard clockwise spindle direction of all common drill presses and power drills, requiring no adapter or special setup.
• 3-35/64 in. Overall Length - sufficient working length to reach full boring depth for typical hinge, frame, and bracket installation without extension accessories.
• Angle-Independent Boring Capability - can create oval and arched openings at any angle, expanding its usefulness beyond perpendicular flat-bottom drilling to decorative and structural joinery work.

Why This Product

• When hinge cups, shelf pin holes, or hardware niches require a perfectly flat bottom, a standard twist bit or spade bit leaves a conical recess that prevents hardware from seating flush - this Forstner bit solves that problem directly with its flat-cutting geometry.
• The SP steel construction is formulated for sustained sharpness during repetitive boring in softwood, making this bit a practical choice for production cabinet and millwork shops where bit longevity directly affects throughput.
• The two-spur design scores the grain ahead of the main cut, which is especially valuable in softwood where fibers are prone to lifting - the result is a hole perimeter clean enough to leave exposed in finished cabinetry.
• At 14mm diameter, this bit covers one of the most common European-style hinge cup sizes, and its ability to bore at any angle means a single bit can handle both standard perpendicular hinge pockets and angled frame or arch cutouts in the same project.
