Product Description
CMT Four Flute Dowel Drill - 6 x 65 x 105mm Left-Hand Rotation is a precision-engineered boring tool from CMT, purpose-built for drilling clean, flat-bottom blind holes in solid wood, chipboard, MDF, laminates, and coated panels on multi-spindle CNC boring centers and panel processing equipment. With a 6mm cutting diameter, 65mm cutting height, and 105mm overall length, this extra-long dowel drill reaches deep into panels for reliable dowel joint preparation in furniture manufacturing and cabinet making. The left-hand (LH) rotation matches spindle configurations found on large industrial boring machines, while the tungsten carbide (HW) head and four spiral flutes keep chips evacuating freely even in deep-hole applications.
Key Features
- HW (Tungsten Carbide) Cutting Head - delivers long service life and consistent bore quality in abrasive engineered panel materials like MDF and chipboard, where high-speed steel tools wear rapidly.
- 2 Precision-Ground HW Cutting Edges (Z2) - provide a clean, true bore diameter of 6mm with each pass, reducing the need for secondary finishing of hole walls.
- 2 Negatively Ground Spurs (V2) - score the material fibers cleanly at the perimeter of the hole before the cutters remove material, preventing tearout and producing crisp bore edges in laminates and coated panels.
- 4 Spiral Flutes - accelerate chip and dust evacuation from deep blind holes, reducing heat buildup and minimizing the risk of chip re-cutting that can degrade hole quality.
- Precision-Balanced Centre Point - keeps the drill on target from entry, preventing walking or skidding at the start of the bore for accurate hole placement in panel layouts.
- PTFE-Coated Cutter Portion - the black or orange PTFE screw coating resists pitch and adhesive buildup on the flutes, maintaining free chip flow and extending intervals between cleanings.
- Super-Strength Steel Body - supports the carbide head under the high-cycle loads of CNC boring centers without flex or vibration that could compromise hole position.
- 10 x 30mm Parallel Shank with Driving Flat and Length-Adjusting Feature - ensures secure, repeatable seating in standard boring machine collets and chucks, with the driving flat transmitting torque reliably and the length-adjusting capability allowing precise depth setup on the machine.
- Left-Hand (LH) Rotation - engineered specifically for left-hand spindle positions on multi-spindle CNC boring centers, ensuring correct cutting geometry and chip direction for those stations.
Why This Product
- The 105mm overall length places this drill in the extra-long category, making it the right choice when standard-length dowel drills cannot reach the required depth for blind holes in thick panels or nested workpieces on CNC boring centers.
- Negatively ground spurs combined with a precision carbide cutting head work together to produce hole walls and flat bottoms that are ready for dowel insertion without additional processing - directly reducing cycle time in high-volume furniture and cabinet production.
- The PTFE coating on the cutter portion addresses one of the most common productivity losses in panel boring - adhesive and pitch buildup on flutes - by actively resisting those deposits so the drill maintains consistent chip evacuation across longer production runs.
- The 10 x 30mm parallel shank with driving flat and length-adjusting capability means this drill can be set up accurately across multiple spindles to maintain consistent hole depth in dowel joint patterns, which is critical for part interchangeability in flat-pack furniture manufacturing.

Frequently Asked Questions
What machines is this dowel drill compatible with?
This drill is designed for use on multi-spindle CNC boring centers and panel processing centers. The 10 x 30mm parallel shank with driving flat is a standard interface for industrial boring machine collets and chucks. It is suited to left-hand (LH) spindle positions on those machines.
Why does this drill have both spurs and four flutes - what does each do?
The 2 negatively ground spurs score the material perimeter before the 2 carbide cutting edges remove the core material, producing clean hole walls and preventing surface tearout in laminates and coated panels. The 4 spiral flutes then evacuate chips rapidly from the bore, which is especially important in deep blind holes where chip buildup would otherwise cause heat and re-cutting.
What is the purpose of the PTFE coating on the cutter portion?
The black or orange PTFE coating applied to the cutter portion of the drill resists the buildup of pitch and adhesive glue on the flutes. In panel materials such as MDF and chipboard, resin and adhesive deposits can restrict chip flow and cause the drill to run hot. The PTFE coating helps maintain free chip evacuation and extends the useful life of the tool between cleanings.
What does "negatively ground spurs" mean and why does it matter for panel materials?
Negatively ground spurs are sharpened with a geometry that scores and severs the surface fibers of the workpiece at the outer edge of the bore diameter before the main cutting edges advance. This approach is particularly effective in laminates, coated panels, and veneered chipboard, where a conventional spur geometry could lift or fracture the decorative surface layer, leaving a torn or chipped edge around the hole.
