CMT 311.100.41 Dowel Drill 10 x 35 x 70mm RH is a solid carbide boring bit engineered for high-precision dowel hole drilling in furniture manufacturing, cabinet making, and panel processing. Built from premium super micrograin carbide, this right-hand rotation drill delivers exceptionally clean bores in hardwood, MDF, particle board, plywood, and veneered composites - making it a reliable choice for CNC routers and high-speed multi-spindle boring units alike.

Key Features

• Solid super micrograin carbide construction (HW material grade) - the entire bit is machined from a single unit of premium carbide sourced from Luxembourg, providing structural integrity and extra safety compared to tipped designs, while enabling an almost infinite number of resharpenings to extend the life of the investment.
• Curved, negatively ground spurs (2 spurs) - the unique tip geometry produces exceptionally clean bore walls and flat-bottomed holes with no rough edges or tearout, which is critical for furniture joinery where visible surfaces and tight dowel fit matter.
• Centre-balanced point - ensures the bit enters the workpiece on-axis with no walking or drift, resulting in precisely located holes that align correctly in dowel connection assemblies.
• Plunge edge extending to the centre of the bit - reduces drilling resistance so the bit cuts through dense substrates faster and with less machine load, directly increasing production throughput on high-speed boring centers.
• Oversized cylindrical head - larger than traditional bit profiles, this geometry resists deflection and wear during prolonged production runs, maintaining bore diameter accuracy over time.
• Extreme-rated sharpening durability - the solid carbide body can be resharpened repeatedly without compromising the bit's structural integrity, reducing long-term tooling cost per bore.
• 10 x 30mm parallel shank - fits standard boring machine chucks and CNC tool holders without adapters, simplifying setup and minimising runout.
• 70mm total length with 35mm cutting height - the extended length enables sufficient boring depth for blind dowel holes in panels while the 35mm cutting zone provides clearance for chip evacuation during deep drilling.
• Right-hand (RH) rotation - compatible with the standard spindle direction of multi-spindle CNC boring machines and boring centers, allowing direct drop-in use without special spindle configuration.

Why This Product

• The solid micrograin carbide body - not a tipped or coated steel shank - means the bit can be resharpened an almost unlimited number of times, keeping tooling costs low in high-volume furniture and cabinet production environments.
• The negatively ground curved spurs create bore quality that meets the clean-entry requirements of veneered panels and coated boards where tearout on the face surface would cause visible defects and rework.
• At 70mm total length with a 10mm diameter, this bit is specifically proportioned for dowel boring depths standard to panel furniture construction, fitting directly into CNC boring centers and multi-spindle units without modification.
• Ideal for difficult composite substrates including particle board and MDF - materials that rapidly degrade ordinary high-speed steel bits - the HW carbide grade retains its cutting edge significantly longer between sharpening intervals.
