Product Description
CMT 314.064.11 Dowel Drill for Through Holes - 1/4" x 35 x 70mm, Right-Hand Rotation is a professional-grade, 2-flute carbide-tipped boring tool engineered for clean, accurate through-hole drilling in panel processing and furniture manufacturing applications. Built on a super-strength steel body with a hardmetal (HW) cutting head and a PTFE-coated spiral, this right-hand dowel drill delivers consistently smooth bore walls through chipboard, MDF, solid wood, laminates, and coated panels. The 70mm overall length and 10x26mm parallel shank with driving flat make it directly compatible with multi-spindle CNC boring machines and panel processing centers that demand precise, repeatable dowel hole placement.
Key Features
- HW (Hardmetal/Carbide) Cutting Head with Precision-Balanced Centre Point - maintains accurate hole positioning on entry, reducing drift and ensuring consistent dowel alignment across production runs.
- 2 Precision-Ground Cutting Edges (Z2) - dual flute geometry produces clean bore walls and smooth hole exits, minimizing tearout and blowout when drilling through panels.
- Super-Strength Steel Body - provides rigidity and resistance to deflection under the high-cycle demands of automated boring equipment and multi-spindle machines.
- PTFE-Coated Spiral Flutes - the orange or black P.T.F.E. coating on the spiral portion prevents pitch and adhesive buildup in the flutes, reducing cleaning time and extending service intervals.
- 2 Spiral Flutes - efficient chip evacuation through the flute design keeps the cutting zone clear, supporting clean through-hole results in dense panel materials like MDF and chipboard.
- Parallel Shank with Driving Flat and Length Adjusting Screw - the 10x26mm shank seats securely in boring machine chucks or adapters, and the adjusting screw allows precise depth setting without additional tooling.
- Right-Hand (RH) Rotation - matched to the standard spindle direction of the vast majority of CNC boring centers and multi-spindle panel processing machines, ensuring direct compatibility without modification.
- 35mm Cutting Height - sufficient cutting length to drill completely through panels, supporting through-hole dowel connections in furniture carcasses and assembled panel components.
Why This Product
- Built for through-hole dowel joinery in panel goods - with a 35mm cutting height and 70mm overall length, this drill is sized specifically to penetrate full panel thickness, making it a practical choice for furniture assembly lines and cabinet shops producing dowel-joined carcasses.
- PTFE flute coating reduces maintenance downtime - in high-volume boring operations where pitch and glue residue accumulate quickly, the coated spiral keeps flutes cleaner longer, meaning less time stopping production to clean tooling.
- Precision-balanced HW centre point for repeatable accuracy - in CNC and multi-spindle applications where dozens or hundreds of holes must land in exactly the same position, the balanced centre point reduces positional error compared to unbalanced tip geometries.
- Driving flat and length adjusting screw for secure, repeatable setup - the parallel shank design locks positively in machine collets and adapters, and the adjusting screw lets operators dial in tool projection quickly, reducing setup time when changing or replacing bits.

Frequently Asked Questions
What is the difference between this through-hole dowel drill and a blind-hole dowel drill?
This drill is specifically designed to bore completely through a panel or workpiece, producing a through hole. The geometry - including the spiral flutes and cutting-edge configuration - is optimized to exit the panel cleanly without blowout, which is the primary challenge in through-hole boring for dowel joinery. A blind-hole dowel drill is designed to stop at a precise depth within the material without exiting the back face.
What machines is this dowel drill compatible with?
The 10x26mm parallel shank with driving flat is designed for use in multi-spindle CNC boring machines, CNC boring centers, and panel processing centers that accept this shank standard. It can also be used in conventional boring machines fitted with an appropriate adapter or chuck that accepts the parallel shank diameter.
What does the PTFE coating on the spiral flutes do?
The orange or black P.T.F.E. (polytetrafluoroethylene) coating applied to the spiral portion of the drill reduces friction and prevents pitch, resin, and adhesive from adhering to the flute surfaces during cutting. In panel processing environments where glue-coated or resin-bonded materials like chipboard, MDF, and laminates are common, this coating helps maintain cutting performance and reduces the frequency of cleaning required between tool changes.
What does the length adjusting screw on the shank do?
The length adjusting screw, located on the parallel shank, allows the operator to set the precise projection of the drill from the machine spindle or chuck face. This makes it straightforward to establish consistent cutting depth across multiple spindles or when replacing a worn drill, which is especially valuable in multi-spindle boring setups where uniform hole depth is required across all drilling positions.
