CMT 310.047.11 Dowel Drill 3/16" x 27 x 57.5mm RH is a precision-engineered, carbide-tipped boring tool from CMT designed for high-accuracy blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Built with a tungsten carbide (HW) cutting head on a super-strength steel body, this right-hand 2-flute dowel drill delivers clean, flat-bottom bores for reliable dowel joinery in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels. The PTFE-coated spiral flutes resist pitch and adhesive buildup, keeping the tool performing cleanly through extended production runs on CNC boring machines and multi-spindle boring centers.

Key Features

• Tungsten carbide (HW) cutting head - delivers long-lasting edge retention when boring abrasive engineered panels and hardwoods, reducing the need for frequent tool changes in production environments.
• 2 precision-ground carbide cutting edges (Z2) - two balanced cutting edges ensure consistent chip removal and a smooth bore surface, resulting in accurate hole geometry for tight-fitting dowel connections.
• 2 negatively ground spurs (V2) - score the material cleanly at the perimeter of the hole before the main cutting edges engage, minimizing tear-out and producing clean bore walls even in veneered or laminated panels.
• PTFE-coated spiral flutes - the orange or black PTFE coating on the spiral portion prevents pitch, resin, and adhesive from bonding to the tool surface, extending tool life and maintaining cutting efficiency between sharpenings.
• Precision-balanced centre point - locates the drill accurately at the target bore position, reducing walk and improving hole placement repeatability across multi-spindle setups.
• Parallel shank with driving flat and length adjusting screw (10 x 27mm) - provides positive engagement in boring machine chucks and spindle holders, preventing slippage and allowing precise depth setting for blind hole drilling.
• Short series total length of 57.5mm - compact overall length suits tight spindle arrangements on multi-spindle CNC boring machines and panel processing centers where clearance between adjacent spindles is limited.
• Right-hand (RH) rotation - compatible with standard right-hand boring machine spindles, making setup straightforward on the majority of CNC boring centers and multi-spindle units.

Why This Product

• The negatively ground spurs combined with the HW carbide cutting head make this drill a strong match for chipboard, MDF, and laminated panel boring - materials that are notorious for chipping at the bore entry - giving furniture and cabinet manufacturers clean holes that require no secondary cleanup.
• The PTFE-coated spiral keeps the flutes clear of adhesive and resin buildup during continuous production runs, reducing downtime caused by clogged or gummed tooling on panel processing centers.
• The 10 x 27mm parallel shank with driving flat and length adjusting screw locks securely into standard boring machine spindle holders, supporting accurate, repeatable depth control for consistent blind holes in dowel joinery applications.
• At 57.5mm total length with a 27mm cutting height, this short-series dowel drill fits compactly in multi-spindle configurations, allowing high-density spindle layouts without sacrificing tool reach or bore quality.
