Product Description
CMT 310.064.12 Dowel Drill 1/4" x 27 x 57.5mm Left-Hand by CMT is a precision-engineered, carbide-tipped boring tool designed for clean, flat-bottom 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 short-series dowel drill delivers consistently accurate results when used in multi-spindle CNC boring machines, boring centers, and panel processing equipment. The PTFE-coated spiral flutes shed pitch, glue, and adhesive residue to keep the tool cutting cleanly through chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels. Left-hand rotation makes it the correct specification for left-hand spindle positions on multi-spindle boring heads.
Key Features
- Tungsten carbide (HW) cutting head with 2 precision-ground cutting edges (Z2) - delivers long tool life and consistent bore quality across high-volume panel and furniture drilling operations.
- 2 negatively ground spurs (V2) - score the material ahead of the cutting edges to produce clean bore walls and sharp, tear-out-free hole perimeters, even in laminates and coated panels.
- PTFE-coated spiral flutes - prevent pitch, adhesive, and resin buildup on the drill body so chips evacuate cleanly and the tool maintains cutting efficiency without frequent cleaning stops.
- Precision-balanced centre point - locates the drill accurately at the start of each bore, reducing wander and ensuring hole-to-hole positioning consistency in dowel joinery and panel drilling work.
- Parallel shank with driving flat and length-adjusting screw (10 x 27mm) - provides secure, repeatable tool registration in multi-spindle boring machine chucks and adapters, with straightforward depth setting.
- Left-hand (LH) rotation - engineered specifically for left-hand spindle positions on multi-spindle boring heads, ensuring proper cutting geometry and clean hole formation in the intended machine configuration.
- Short-series overall length of 57.5mm - keeps the drill compact for tight spindle spacing on multi-spindle boring machines commonly used in furniture and cabinet production.
Why This Product
- The carbide (HW) construction combined with negatively ground spurs makes this drill a reliable choice for clean blind-hole boring in laminated panels and coated board - materials that quickly dull lower-quality tools and produce ragged entry edges without proper spur geometry.
- The PTFE-coated spiral addresses one of the most common productivity problems in high-volume boring operations - adhesive and pitch accumulation on the drill body - so operators spend less time cleaning tools and more time running parts.
- Left-hand rotation and the 10 x 27mm parallel shank with driving flat are purpose-matched to the left-hand spindle positions found on multi-spindle CNC boring machines, making this a direct, correct-specification replacement or upgrade rather than a compromise fit.
- The 1/4" (approximately 6.35mm) nominal diameter with a 27mm cutting height covers the standard dowel pin bore depth requirements used throughout flat-pack furniture and cabinet carcass construction, giving woodworking shops a tool sized for their most common joinery operations.

Frequently Asked Questions
What materials can this dowel drill be used on?
This drill is designed for boring in solid wood (hardwood and softwood), chipboard, MDF, HDF, plywood, laminates, and coated panels. The negatively ground spurs and carbide cutting edges maintain clean bore walls and sharp entry perimeters across all of these materials, including the abrasive surfaces found on laminated and coated panels.
Why does this drill have a left-hand (LH) rotation and when do I need it?
Left-hand rotation is required for left-hand spindle positions on multi-spindle boring heads and CNC boring machines. Using the correct rotation direction is essential - a left-hand drill in a right-hand spindle, or vice versa, will not cut properly and can damage the tool or workpiece. Always confirm your machine spindle rotation direction before selecting LH or RH tooling.
What does the PTFE coating on the spiral flutes do?
The PTFE coating applied to the spiral portion of the drill reduces friction and prevents pitch, glue, and adhesive residue from bonding to the drill body. This keeps chips evacuating cleanly during boring and reduces the frequency of tool cleaning stops, helping maintain consistent performance over longer production runs.
What shank does this dowel drill use and how is depth adjusted?
This drill uses a 10 x 27mm parallel shank with a driving flat and a length-adjusting screw. The driving flat provides positive torque transfer in the machine chuck or adapter, and the adjusting screw allows the drill projection length to be set for precise and repeatable boring depth control.
