Product Description
CMT 310.100.12 Dowel Drill - 10 x 27 x 57.5mm Left-Hand Rotation is a precision-engineered 2-flute dowel drill from CMT, built for clean, repeatable blind-hole boring in furniture manufacturing, cabinet making, and panel processing applications. Designed for left-hand (LH) rotation, this short-series drill fits multi-spindle CNC boring machines and panel processing centers where accurate dowel joint drilling in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels is required. The tungsten carbide (HW) cutting head and PTFE-coated spiral work together to deliver fast stock removal, smooth bore walls, and extended tool life in high-production environments.
Key Features
- Tungsten Carbide (HW) Cutting Head with 2 Precision-Ground Edges (Z2) - hard carbide material holds a sharp edge longer than standard steel, reducing retool downtime and maintaining consistent hole quality across long production runs.
- 2 Negatively Ground Spurs (V2) - negatively ground geometry scores the material boundary cleanly before the flutes remove waste, producing flat-bottom blind holes with minimal tearout on veneered panels, laminates, and coated surfaces.
- PTFE-Coated Spiral Portion - the low-friction orange or black P.T.F.E. coating prevents pitch, resin, and adhesive buildup on the flutes, keeping the cutting action smooth and reducing cleaning frequency in continuous-use settings.
- Precision-Balanced Centre Point - the HW centre point self-locates accurately at the target bore position, reducing drill walk and ensuring repeatable hole placement critical for tight-tolerance dowel connections.
- Super-Strength Steel Body - the premium-quality steel shank resists flex and vibration during high-speed boring, supporting dimensional accuracy across the 27mm cutting height.
- Parallel Shank with Driving Flat and Length-Adjusting Screw - the 10 x 27mm parallel shank seats securely in multi-spindle boring heads or chuck adapters, while the adjusting screw allows precise depth setting without dedicated tooling.
- Left-Hand (LH) Rotation - engineered specifically for LH spindle positions on multi-spindle CNC boring machines and boring centers, ensuring correct chip evacuation and cutting geometry on the corresponding side of the machine head.
- Short Series Total Length of 57.5mm - the compact 57.5mm overall length fits tight spindle pitch configurations common in 32mm-system cabinet boring without clearance conflicts.
Why This Product
- The negatively ground spur geometry combined with the precision HW centre point delivers clean, flat-bottom blind holes with no tearout - making this drill the right choice for visible or veneered panel faces where surface quality directly affects finished product appearance.
- The PTFE-coated spiral reduces pitch and adhesive accumulation during high-volume panel processing, extending intervals between cleaning and helping maintain consistent cutting performance throughout long production shifts.
- The left-hand rotation designation makes this drill a direct, compatible replacement for LH spindle positions on multi-spindle CNC boring machines and panel processing centers - eliminating the guesswork of rotation matching when equipping or re-equipping a boring head.
- The parallel shank with a driving flat and length-adjusting screw provides secure, adjustable seating in boring machine spindles, supporting accurate depth control for dowel joint drilling where consistent hole depth is essential to joint integrity.

Frequently Asked Questions
What does left-hand (LH) rotation mean, and how do I know if this drill is correct for my machine?
Left-hand rotation means the drill is designed to cut when spinning counter-clockwise (when viewed from the shank end). Multi-spindle CNC boring machines and panel processing centers typically have both right-hand and left-hand spindles arranged symmetrically. This drill is intended for the LH spindle positions. Check your machine's spindle layout or the boring head documentation to confirm which positions require LH tooling before ordering.
What materials can this dowel drill be used on?
This drill is suited for boring in chipboard, MDF, HDF, hardwood, softwood, plywood, laminates, and coated panels. The negatively ground spurs and HW carbide cutting edges are designed to produce clean entry and flat-bottom blind holes across all of these panel and solid-wood materials commonly used in furniture and cabinet manufacturing.
What is the purpose of the PTFE coating on the spiral, and does it wear off?
The P.T.F.E. coating on the spiral portion of the drill reduces friction between the flutes and the material being bored. This prevents pitch, resin, and adhesive from sticking to the flute surface, which would otherwise slow chip evacuation and degrade cutting performance. The coating is applied to the spiral specifically to maintain smooth flute action during production use.
What is the difference between the 57.5mm total length and the 27mm cutting height?
The 27mm cutting height (also referred to as cutting length or flute length) is the active portion of the drill that removes material - this determines the maximum useful depth of the blind hole you can bore. The 57.5mm total length is the full end-to-end measurement of the drill including the shank, which is relevant for determining tool clearance and reach within the boring machine spindle.
