CMT Forstner Bit Set - 5 Piece, 8-10mm Shank, Right-Hand Rotation is a high-performance metric forstner bit collection engineered for clean, flat-bottomed hole drilling in wood-based materials. Offered by CMT, this 5-piece set covers the most popular metric diameters - 15mm, 20mm, 25mm, 30mm, and 35mm - making it a practical choice for cabinetry, hinge installation, and precision pocket drilling with a drill press or handheld electric drill. The stagger tooth design on larger-diameter bits produces sharp entry points, straight sidewalls, and flat hole bottoms, delivering accurate results in hardwood, softwood, plywood, MDF, and chipboard.

Key Features

• 5-piece set spanning 15mm, 20mm, 25mm, 30mm, and 35mm diameters - covers the most commonly needed metric sizes in a single purchase, reducing the need for individual bit sourcing
• Stagger tooth design on larger-diameter bits - produces sharp holes with straight sides and flat bottoms, minimizing tearout and improving hole quality in demanding applications
• Compatible with drill presses, electric drills, and cordless drills - versatile tool compatibility means you can use these bits across a wide range of workshop and job site setups
• 8mm to 10mm shank diameter range (varies by bit size) - ensures secure chuck grip across different drilling platforms without adapter requirements
• 2 spurs per bit - guide the cutting path precisely, keeping holes centered and reducing drift during entry
• Right-hand rotation - standard RH direction works with virtually all conventional drill chucks and drill presses without special setup
• Special steel (SP) material construction - provides the hardness and edge retention needed for repeated use in hardwood and engineered wood panels
• 3-35/64 in. total length - gives adequate reach for through-hole and deep pocket applications without excessive bit flex

Why This Product

• The five included metric diameters (15mm through 35mm) address the most common hinge boring and pocket drilling sizes used in European-style cabinet construction, making this set a practical all-in-one solution rather than a collection of mismatched individual bits.
• The stagger tooth geometry on larger bits means cleaner cuts in harder materials - the flat-bottomed hole result is especially important in hinge installation and joinery work where a precise fit is required.
• Compatibility across drill presses, corded electric drills, and cordless drills means this set works in a fixed workshop setting as well as on-site, without needing separate tools for different environments.
• Packaged in a clamshell case, the set keeps all five bits organized and protected between uses, preserving cutting edge sharpness and making the correct size easy to locate at a glance.
