Product Description
CMT Four Flute Dowel Drill - 12 x 65 x 105mm Right-Hand is a professional-grade boring tool engineered for clean, deep blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this extra-long dowel drill delivers precision-balanced performance in chipboard, MDF, hardwood, softwood, and laminated panels. The 105mm total length and 65mm cutting depth make it especially well suited for large CNC boring centers and multi-spindle machines requiring reach that standard-length drills cannot achieve.
Key Features
- HW (Tungsten Carbide) Cutting Head with Precision-Balanced Centre Point - the carbide tip maintains accurate hole registration and prevents wandering on entry, producing consistently centered dowel bores even in dense engineered panels.
- 2 Precision-Ground HW Cutting Edges (Z2) - dual carbide cutting edges shear material cleanly at the bore floor, delivering flat-bottomed holes that seat dowels firmly and squarely for strong joinery.
- 2 Negatively Ground Spurs (V2) - the negatively set spur geometry scores the material perimeter ahead of the cutting edges, preventing surface tearout and producing clean, crisp hole walls even in coated and laminated panels.
- 4 Spiral Flutes - four flutes evacuate chips rapidly from the bore, reducing heat buildup and clogging during deep-hole drilling operations common in CNC panel processing.
- PTFE-Coated Cutter Portion - the black or orange PTFE coating on the spiral surfaces prevents pitch and adhesive buildup, extending tool life and reducing downtime between cleanings.
- Super-Strength Steel Body - the robust steel shank and body resist flex and vibration under the high-cycle demands of automated boring centers, maintaining dimensional accuracy across long production runs.
- 10 x 30mm Parallel Shank with Driving Flat and Length-Adjusting Feature - the standardized shank design ensures positive drive engagement and allows precise depth setting in compatible boring machine chucks and adapters.
- Right-Hand (RH) Rotation - designed for standard right-hand spindle configurations found on the majority of CNC boring centers and multi-spindle panel machines.
Why This Product
- Extra-Long Reach for Deep Blind Holes - the 105mm overall length and 65mm cutting height provide access depth that standard dowel drills cannot match, making this the right tool when boring centers require additional clearance or when drilling through thick panel stacks.
- Optimized for CNC and Multi-Spindle Production - the precision-balanced carbide head, four-flute chip evacuation, and driving-flat shank are all designed for the high-speed, high-cycle demands of automated CNC boring centers and panel processing lines where repeatability and speed matter.
- Tearout-Free Results in Coated and Laminated Materials - the combination of negatively ground spurs and precision carbide edges makes this drill suitable for chipboard, MDF, HDF, laminates, and coated panels where surface finish quality is critical to the finished product.
- PTFE Coating Reduces Maintenance Interruptions - by resisting pitch and glue adhesion on the spiral, the PTFE-coated cutter portion stays cleaner longer in production environments where adhesive-coated or resin-bonded panels are processed continuously.

Frequently Asked Questions
What materials can this dowel drill be used on?
This drill is designed for use in solid wood (hardwood and softwood), chipboard, MDF, HDF, plywood, laminates, and coated panels. The negatively ground spurs and precision carbide cutting edges are specifically suited to engineered sheet goods and surface-sensitive laminated materials where tearout-free boring is required.
What type of machine does this drill require?
This drill is intended for use in multi-spindle CNC boring centers, CNC boring centers, and panel processing machines equipped with a chuck or adapter compatible with the 10 x 30mm parallel shank with driving flat. The driving flat ensures positive rotational engagement and the length-adjusting feature allows precise depth setting in the machine spindle.
Why does this drill have four flutes if it only has two cutting edges?
The four spiral flutes are dedicated chip evacuation channels that remove swarf quickly from the bore during deep-hole drilling. The two HW precision-ground cutting edges (Z2) handle the actual cutting action, while the two negatively ground spurs (V2) score the hole perimeter. The four-flute configuration is essential for maintaining clean holes and preventing clogging when drilling to the full 65mm cutting depth in dense panel materials.
What does the PTFE coating on this drill do?
The black or orange PTFE coating applied to the cutter portion of the spiral prevents pitch and glue from adhering to the tool surface during drilling. This is especially valuable in production environments where resin-bonded, adhesive-treated, or pre-glued panels are processed, as it reduces buildup that would otherwise degrade cutting performance and require frequent tool cleaning.
