The CMT Dowel Drill Xtreme is a precision-engineered 10mm diameter boring tool built for high-volume panel processing and furniture manufacturing. Constructed from HWM solid carbide and featuring an Xtreme sharpening profile, this right-hand rotating dowel bit delivers clean, flat-bottomed blind holes in chipboard, MDF, hardwood, plywood, laminates, and coated panels. The long-series 70mm overall length paired with a 10x25mm parallel shank makes it compatible with multi-spindle CNC boring machines and panel processing centers demanding consistent, repeatable bore quality at production speeds.

Key Features

• HWM Solid Carbide Construction - the full-carbide body resists wear even during continuous production runs, significantly extending tool life between resharpening cycles and reducing downtime on multi-spindle boring equipment.
• Xtreme Sharpening Profile - the precision Xtreme grind geometry produces exceptionally sharp cutting edges that enter material cleanly, reducing fiber tearout and delivering smooth bore walls in engineered wood panels and laminates.
• 2 Flutes with 2 Precision-Ground Spurs - dual spurs score the perimeter of the bore ahead of the cutting edges, creating crisp, clean entry points in chipboard, MDF, and coated surfaces where surface quality is critical.
• 35mm Cutting Height in a 70mm Long-Series Body - the extended length allows deeper boring depths than short-series equivalents, making this bit ideal for blind holes in thicker panels and furniture components that require precise depth control.
• 10x25mm Parallel Shank - the 10mm diameter shank at 25mm engagement length provides a positive, stable grip in CNC boring machine chucks and multi-spindle heads, minimizing runout and ensuring accurate bore positioning under high-cycle conditions.
• Right-Hand (RH) Rotation - matches the standard spindle direction of the vast majority of industrial panel boring machines and CNC boring centers, allowing direct installation without adapter modifications.

Why This Product

• At 10mm diameter with a 35mm cutting height, this dowel drill covers one of the most common bore sizes in cabinet and furniture panel joining, eliminating the need for multiple tool changes when processing high quantities of shelf pin, dowel, or connector holes.
• The HWM carbide construction combined with the Xtreme sharpening specification means the cutting edges hold their geometry longer in abrasive engineered wood materials like MDF and chipboard - materials that rapidly degrade lower-grade tooling.
• The 70mm long-series body length gives operators the clearance needed to bore into panel stacks or fixtures where a short-series bit would not reach, expanding versatility across a wider range of panel processing setups.
• With 2 spurs and 2 cutting flutes working together, this bit produces flat-bottomed holes with clean entry and exit profiles - a key quality requirement in visible furniture panels where surface finish directly affects the finished product.
