Product Description
CMT Four Flute Dowel Drill 6 x 65 x 105mm Right-Hand by CMT is an extra-long carbide-tipped boring tool engineered for precision dowel hole drilling in furniture manufacturing, cabinet making, and panel processing applications. With a 6mm cutting diameter and a 65mm cutting height on a 105mm total length body, this drill reaches deep blind holes that standard-length dowel drills cannot access. The hardened tungsten carbide (HW) cutting head, paired with four spiral flutes and a PTFE-coated cutter body, delivers clean, splinter-free bores in solid wood, chipboard, MDF, HDF, laminates, and coated panels. Designed for right-hand rotation, this tool is a dependable choice for multi-spindle CNC boring centers and large panel processing equipment.
Key Features
- HW (Tungsten Carbide) Cutting Head - precision-grade carbide material holds a sharp edge longer than standard steel, reducing downtime for tool changes during high-volume production runs.
- Precision Balanced Centre Point - centers the drill accurately at the start of each bore, eliminating wandering and ensuring consistent hole placement for tight-tolerance dowel joinery.
- 2 Precision-Ground Cutting Edges (Z2) - dual carbide cutting edges shear material cleanly on entry and exit, producing flat-bottomed blind holes with minimal tearout in chipboard, MDF, and laminates.
- 2 Negatively Ground Spurs (V2) - negatively set spurs score the perimeter of the bore before the main cutters engage, resulting in crisp, clean bore walls with no rough edges even in coated or laminated panels.
- 4 Spiral Flutes - four flutes evacuate chips rapidly from deep blind holes, preventing clogging and overheating that can damage the workpiece surface or the tool itself.
- PTFE Coating on Cutter Portion - the black or orange PTFE coating on the spiral prevents pitch and glue buildup, extending tool life and maintaining consistent cutting performance across panel materials.
- Super-Strength Steel Body - a robust steel shank and body resist deflection under the lateral forces common in multi-spindle CNC boring operations, supporting accurate hole depth and position.
- Parallel Shank with Driving Flat and Length Adjusting - the 10 x 30mm parallel shank with a driving flat locks securely in boring machine chucks or adapters, and the length-adjusting feature allows precise setting of drilling depth for repeatable results.
- 65mm Cutting Height on a 105mm Body - the extra-long series profile provides access to deep blind holes required for thick-panel furniture components and cabinet carcass assembly.
- Right-Hand Rotation - RH rotation is compatible with the vast majority of CNC boring centers and multi-spindle machines used in panel furniture production.
Why This Product
- The 105mm total length and 65mm cutting height make this drill the right choice when standard short-series dowel drills fall short - specifically in thick-panel applications or deep-pocket boring on large CNC boring centers where reach matters.
- The combination of a precision balanced centre point, two ground cutting edges, and two negatively ground spurs produces clean, accurate holes in laminated and coated panels without delamination or surface tearout - critical for visible furniture faces.
- PTFE coating on the spiral reduces pitch and adhesive buildup when drilling chipboard, MDF, and glued laminates, keeping the tool running cleanly through long production cycles without frequent cleaning stops.
- The 10 x 30mm parallel shank with driving flat and length-adjusting capability integrates directly into standard boring machine tooling systems, making setup fast and repeatable across multi-spindle configurations.

Frequently Asked Questions
What machines is the CMT 372.060.11 compatible with?
This dowel drill is designed for use on multi-spindle CNC boring centers, CNC boring centers, panel processing centers, and boring machines fitted with a compatible adapter or chuck that accepts a 10 x 30mm parallel shank with a driving flat.
Why does this drill have four flutes instead of the two flutes found on standard dowel drills?
The four spiral flutes provide more aggressive chip evacuation from deep blind holes, which is especially important when boring to the full 65mm cutting depth. More flutes mean chips clear faster, reducing heat buildup and the risk of clogging in materials like MDF and chipboard that generate fine, compacting dust.
What is the purpose of the PTFE coating on the cutter portion?
The black or orange PTFE coating on the spiral reduces friction and prevents pitch, resin, and adhesive from bonding to the tool surface. This is particularly valuable when boring through chipboard, glued laminates, and coated panels, where resin-based binders can quickly load up an uncoated tool and degrade cutting performance.
What is the difference between negatively ground spurs and standard spurs?
Negatively ground spurs are oriented to score the outer perimeter of the hole ahead of the main cutting edges, severing surface fibers and panel coatings cleanly before the body of the drill passes through. This produces a cleaner bore wall and prevents the delamination or chipping on the face of coated or laminated panels that can occur with positively ground or unground spurs.
