CMT 309.120.11 Dowel Drill - 12 x 43 x 70mm Right-Hand by CMT is a precision-engineered carbide-tipped boring tool designed for clean, flat-bottom blind holes in furniture panel processing, cabinet making, and dowel joinery work. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this 12mm diameter dowel drill delivers accurate, repeatable results in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels. The long-series 70mm overall length accommodates deeper drilling depths, making it a reliable choice for thicker panel stock and multi-spindle boring applications.

Key Features

• HW (Tungsten Carbide) Cutting Head - hard carbide material holds a sharp edge longer under continuous production use, reducing tool changes and maintaining consistent hole quality over time.
• 2 Precision-Ground Cutting Edges (Z2) - dual carbide cutting edges shear material cleanly on entry and through the cut, producing smooth bore walls and accurate diameter sizing in every pass.
• 2 Negatively Ground Spurs (V2) - negatively sharpened spurs score the wood fibers ahead of the main cutting edges, eliminating tearout at the rim of the hole for a clean, finished edge on both face veneers and laminates.
• 4 Spiral Flutes - four flutes efficiently evacuate chips and dust from the bore during drilling, preventing chip packing that can cause overheating or hole-wall damage.
• PTFE-Coated Cutter Portion - the black or orange PTFE coating on the spiral reduces friction and resists pitch and adhesive buildup, keeping the tool running freely and extending service life in glued or coated panel materials.
• Precision-Balanced Centre Point - the HW centre point self-locates accurately on the workpiece, minimizing drill walk and ensuring hole placement aligns precisely with CNC or multi-spindle boring grid layouts.
• 10 x 20mm Parallel Shank with Driving Flat and Length-Adjusting Screw - the parallel shank format fits standard boring machine chucks and multi-spindle heads, while the driving flat prevents rotation slip and the adjusting screw allows precise depth setting without dedicated tooling.
• Right-Hand (RH) Rotation - standard clockwise rotation is compatible with the vast majority of CNC boring centers, panel processing centers, and multi-spindle boring machines.
• Long-Series 70mm Overall Length - the extended body provides the reach needed for deeper blind holes in thicker panel assemblies, expanding the range of joint depths achievable without a tool change.

Why This Product

• Clean holes in finished panel materials - the combination of negatively ground spurs and precision carbide cutting edges means veneer faces, laminates, and coated surfaces come out of the bore without fraying or chipping, protecting finished workpieces in furniture and cabinetry production.
• Designed for production boring environments - the 10 x 20mm parallel shank with driving flat and length-adjusting screw is engineered for fast, secure mounting in multi-spindle CNC boring machines and panel processing centers, minimizing setup time between runs.
• Longer service intervals in adhesive-heavy applications - the PTFE coating on the cutter portion resists glue and pitch adhesion, so the tool maintains cutting performance even in operations where pre-glued dowels or adhesive-coated panels are common.
• Versatile across common panel and solid wood substrates - with an HW carbide head rated for chipboard, MDF, HDF, hardwood, softwood, plywood, and laminates, a single tool covers the full range of materials found in a typical cabinet shop or furniture plant.
