Product Description
CMT 310.013.20 Dowel Drill by CMT is a 1.3mm (3/64") diameter, two-flute carbide boring bit engineered for high-precision blind hole drilling in panel processing and cabinet manufacturing applications. With a right-hand and left-hand (RH/LH) rotation design and a 10x30mm parallel shank, this short-series dowel drill is purpose-built for use in multi-spindle CNC boring machines, CNC boring centers, and panel processing equipment. The solid carbide (HWM) construction delivers clean, flat-bottom holes with minimal tearout across a wide range of materials including solid wood, chipboard, MDF, HDF, plywood, laminates, and coated panels - making it a dependable choice for furniture production, cabinetry, and millwork operations that demand consistent bore quality.
Key Features
- 1.3mm (3/64") Cutting Diameter with 5mm Cutting Height - engineered for compact, precise dowel holes where tight tolerances and repeatable depth control are essential in panel and solid wood joinery.
- Two-Flute Design - dual flutes evacuate chips efficiently during blind hole drilling, reducing heat buildup and producing cleaner hole walls with every pass.
- HWM Solid Carbide Construction - tungsten carbide material maintains sharp cutting edges far longer than high-speed steel alternatives, translating to extended tool life and fewer changeovers in high-volume production environments.
- Right-Hand and Left-Hand (RH/LH) Rotation Compatibility - a single bit works on both right- and left-rotating spindles, reducing the number of dedicated tools required for multi-spindle machine setups.
- 10x30mm Parallel Shank - the 25/64" x 1" shank interfaces reliably with standard boring machine chucks and adapters, ensuring stable clamping and minimal runout during high-speed operation.
- Short-Series Profile (57.5mm Overall Length) - the compact 2-17/64" overall length reduces deflection and vibration, contributing to more consistent hole geometry and improved surface finish inside the bore.
- PTFE Non-Stick Coating - prevents resin, pitch, and adhesive buildup on the flutes, reducing cleaning frequency and keeping the bit performing at full efficiency for longer between maintenance intervals.
- Precision-Ground Negatively Set Spurs - cleanly score the material perimeter before the main cutting edge engages, producing flat-bottomed holes and chip-free entry points even in laminated or coated panel materials.
Why This Product
- Designed for double-sided spindle configurations - the RH/LH rotation capability means this bit mounts and performs correctly on both sides of a multi-spindle boring head without requiring two separate part numbers, streamlining inventory and setup time.
- Carbide construction supports high-volume production cycles - HWM solid carbide holds an edge under the continuous demands of CNC boring centers and panel processing centers, reducing downtime from dull tool replacements compared to softer tool materials.
- PTFE coating addresses a real production pain point - adhesive and resin-coated panels are common in cabinetry and furniture production; the non-stick coating actively resists contamination buildup, keeping cycle times consistent and reducing manual cleaning between production runs.
- Short-series geometry minimizes deflection in tight boring heads - at 57.5mm total length, this bit is optimized for the compact spindle spacing typical of industrial multi-spindle boring machines, where longer bits would create interference or runout issues.

Frequently Asked Questions
Can this dowel drill be used on both right-hand and left-hand rotating spindles?
Yes. The CMT 310.013.20 is rated for both right-hand (RH) and left-hand (LH) rotation, making it directly compatible with both sides of a multi-spindle boring head without requiring separate right- and left-handed bit inventories.
What shank size does this bit use, and what machines will it fit?
This bit uses a 10x30mm parallel shank (25/64" diameter, 1" length). It is compatible with multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines equipped with an appropriate adapter or chuck that accepts this shank size.
What is the cutting diameter and cutting depth of the CMT 310.013.20?
The cutting diameter is 1.3mm (3/64") and the cutting height - the usable cutting depth - is 5mm (13/64"). These dimensions are suited to precision blind hole boring for dowel joinery in panel and solid wood applications.
Why does this bit have a PTFE coating, and what materials benefit most from it?
The PTFE non-stick coating on the flutes resists buildup of pitch, resin, and adhesive - substances commonly encountered when boring laminated panels, coated boards, MDF, and chipboard. This helps maintain consistent cutting performance and reduces the frequency of cleaning during production runs.
