Product Description
CMT 313.060.11 Dowel Drill for Through Hole - 6 x 27 x 57.5mm Right-Hand is a precision-engineered, 2-flute carbide-tipped boring tool built for clean, accurate through-hole drilling in panel processing and furniture manufacturing applications. Designed for use in multi-spindle CNC boring machines and industrial boring centers, this right-hand rotation drill features a tungsten carbide (HW) cutting head, a PTFE-coated spiral body, and a parallel shank with a driving flat and length-adjusting screw - delivering fast, repeatable results in chipboard, MDF, hardwood, plywood, and coated panels. When a through-hole dowel connection demands a clean entry and a blowout-free exit, this CMT drill is configured specifically for that geometry.
Key Features
- 2-flute through-hole geometry (Z2) - two precision-ground cutting edges optimized for through-hole boring mean cleaner exit cuts and reduced blowout risk compared to flat-bottom configurations, keeping finished panel edges looking professional.
- Tungsten carbide (HW) cutting head - hard-metal construction maintains a sharp edge longer through abrasive engineered wood products like MDF, chipboard, and laminates, reducing tool changes and downtime on the production line.
- PTFE-coated spiral flutes - the orange or black P.T.F.E. coating on the spiral portion prevents pitch and adhesive buildup, so chips evacuate freely and the bit runs cooler during high-volume panel processing.
- Precision-balanced centre point - the HW head incorporates a precision balanced centre point that locates the drill accurately on the panel surface, helping to maintain tight positional tolerances for dowel alignment in furniture assembly.
- Parallel shank with driving flat and length-adjusting screw - the 10 x 26mm shank seats securely in standard boring machine chucks and multi-spindle heads, while the length-adjusting screw allows fine depth calibration without additional tooling.
- Super-strength steel body - the steel core resists flex and vibration under the high-cycle loads of automated panel lines, contributing to consistent hole diameter and roundness across long production runs.
- Right-hand (RH) rotation - matches the standard spindle direction of the vast majority of CNC boring centers and multi-spindle machines, making this a drop-in fit for conventional setups.
Why This Product
- Built for through-hole dowel joinery - unlike flat-bottom drill geometries, the 313.060.11 is engineered specifically for through-hole applications, so the cutting edges clear the panel completely and leave a clean, chip-free bore on both faces - critical for visible furniture panels.
- PTFE coating extends tool life in glue-up environments - production shops that drill panels near assembly areas deal with airborne adhesive mist and pitch contamination; the coated spiral sheds these deposits rather than accumulating them, keeping performance consistent longer.
- Compact 57.5mm overall length fits tight multi-spindle heads - the 57.5mm total length and 10 x 26mm shank are sized for the close spindle spacing of industrial boring machines, making this drill a practical fit for dense multi-head configurations without clearance issues.
- Precise 6mm cutting diameter for standard dowel connections - the 6mm diameter pairs directly with common 6mm round dowels used throughout flat-pack and RTA furniture production, eliminating sizing mismatches and ensuring snug, accurate joints.

Frequently Asked Questions
What is the difference between a through-hole dowel drill and a flat-bottom dowel drill?
A through-hole dowel drill, like the CMT 313.060.11, uses a cutting geometry designed to pass completely through the workpiece, producing a clean bore on both the entry and exit faces. A flat-bottom drill is designed to stop at a set depth and leave a flat-bottom blind hole. The through-hole version is the correct choice when the dowel or fastener must pass fully through the panel or when clean exit is required on both faces.
What does the PTFE coating on the spiral flutes do?
The P.T.F.E. coating applied to the spiral portion of the 313.060.11 acts as a non-stick surface that prevents pitch, resin, and adhesive from bonding to the flutes during drilling. This keeps chips evacuating freely, reduces heat buildup, and helps the bit maintain clean cutting performance over a longer service life - especially in processed wood products like MDF and chipboard that tend to generate fine, sticky dust.
Will this bit work in a hand-held drill or router?
The 313.060.11 features a 10 x 26mm parallel shank with a driving flat and a length-adjusting screw, which is a configuration designed for industrial boring machines, multi-spindle CNC boring heads, and boring centers that accept this shank format. It is not a standard round shank compatible with a hand-held drill chuck. Confirm that your machine accepts a 10mm parallel shank with driving flat before ordering.
How does the precision-balanced centre point affect drilling accuracy?
The HW (tungsten carbide) head on this drill incorporates a precision-balanced centre point, which locates the tip exactly on the intended bore position before the cutting edges engage. This reduces walking or drift at the start of the cut, which is especially important in multi-spindle setups where dozens of holes must align precisely for dowel joints to fit together correctly in furniture assembly.
