CMT 308.100.11 Dowel Drill - 10 x 30 x 57.5mm Right-Hand is a short-series, 4-flute dowel drilling bit engineered by CMT for fast, repeatable blind-hole production in furniture manufacturing, cabinet making, and panel processing. Built on a super-strength steel body tipped with precision-ground tungsten carbide (HW), this 10mm diameter boring tool delivers clean, flat-bottom holes in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels - making it a go-to choice for dowel joinery on multi-spindle CNC boring machines and panel processing centers alike.

Key Features

• Super-strength steel body with HW (tungsten carbide) cutting head - the carbide-tipped construction resists wear during high-cycle production runs, maintaining cutting precision longer than standard high-speed steel bits in abrasive panel materials like MDF and chipboard.
• 2 precision-ground HW cutting edges (Z2) - dual carbide cutting edges provide balanced chip removal and consistent bore geometry, resulting in tight-tolerance holes that seat dowels accurately for strong, repeatable joints.
• 2 negatively ground spurs (V2) - the negative-angle spur geometry severs wood fibers cleanly at the bore perimeter before the cutting edges engage, eliminating tearout and producing smooth, splinter-free hole walls even in laminated and coated panels.
• 4 spiral flutes - four flutes evacuate chips efficiently from the bore during drilling, reducing heat buildup, minimizing clogging, and keeping the cutting zone clear for cleaner holes at production feed rates.
• PTFE (P.T.F.E.) coating on the cutter portion - the black or orange PTFE coating prevents pitch, resin, and glue buildup on the spiral, reducing friction and extending tool life between resharpening intervals.
• Precision-balanced centre point (HW) - the carbide centre point locates the drill accurately on the workpiece at the moment of contact, preventing walking or skidding and ensuring hole placement matches CNC bore patterns exactly.
• Parallel shank (10 x 20mm) with driving flat and length-adjusting screw - the driving flat transfers torque without slippage in the spindle, while the length-adjusting screw allows precise depth setting on multi-spindle boring heads and CNC boring centers.
• Right-hand (RH) rotation - matched to standard right-hand spindle boring machines and CNC boring centers for plug-and-play compatibility with conventional setups.

Why This Product

• The negatively ground spurs combined with the precision-balanced HW centre point make this bit especially well-suited for drilling blind dowel holes in laminated and coated panels where surface tearout is not acceptable - common in furniture and cabinet carcass construction.
• At 57.5mm overall length with a 30mm cutting height, this short-series dowel drill is dimensioned for the tight spindle spacing found on multi-spindle CNC boring machines and panel processing centers, fitting where longer bits cannot.
• The PTFE-coated spiral and 4-flute chip evacuation design work together to sustain cutting performance across high-volume production cycles - reducing downtime caused by pitch buildup or chip packing in the bore.
• The 10 x 20mm parallel shank with driving flat and length-adjusting screw allows secure mounting and repeatable depth calibration across a wide range of boring machine setups, supporting consistent joint quality without time-consuming manual checks.
