Product Description
CMT Two Flute Dowel Drill for Through Holes - 6x44x77mm Right Hand is a precision-engineered 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 panel processing centers, this 6mm carbide-tipped dowel drill features a hardmetal (HW) cutting head, two precision-ground cutting edges, and a PTFE-coated spiral body that keeps the flutes clear of pitch and resin during continuous production use. Whether you are drilling dowel connection holes in chipboard, MDF, hardwood, or coated panels, this right-hand rotation drill delivers consistent bore quality from entry to exit.
Key Features
- Hardmetal (HW) cutting head with precision balanced centre point - delivers accurate hole positioning and clean entry without deflection, reducing reject rates in high-volume panel boring operations.
- Two precision-ground cutting edges (Z2) - produce smooth, uniform bore walls on through-hole applications, minimizing tearout on both entry and exit faces of the panel.
- Two spiral flutes for chip evacuation - pull chips up and out of the bore as drilling progresses through the full 44mm cutting depth, preventing chip packing and overheating during deep through-hole drilling.
- PTFE-coated spiral portion (orange or black) - resists pitch, resin, and glue buildup on the flutes, extending tool life between sharpenings and maintaining consistent feed performance across materials like laminates and coated panels.
- Super-strength steel body - provides rigidity and vibration resistance throughout the 77mm total length, supporting accurate boring at the speeds and feeds typical of automated boring centers.
- Parallel shank 10x26mm with driving flat and length adjusting screw - ensures secure, repeatable seating in multi-spindle boring machine chucks or adapters, and allows precise depth setting without additional tooling fixtures.
- Right-hand (RH) rotation - matches the standard spindle direction of the majority of CNC boring centers and multi-spindle boring machines used in furniture panel processing.
- Through-hole geometry with 44mm cutting height - specifically optimized for drilling complete through holes in thick panels, not flat-bottom pocket boring, ensuring correct chip flow and geometry for dowel joint applications.
Why This Product
- Built for deep through-hole performance in thick panels - with a 44mm cutting height and 77mm total length, this drill reaches through panel thicknesses where standard short-series dowel drills fall short, making it the right choice for thicker furniture carcass and panel components.
- PTFE coating reduces downtime in continuous production - the coated spiral resists the pitch and adhesive residues common when boring chipboard, MDF, and laminated panels, so tools stay cleaner longer and sharpening intervals are extended.
- Precision balanced centre point supports accurate dowel alignment - the HW head with balanced centre point keeps hole position true at the start of each bore, which is critical when drilling matched dowel holes that must align precisely during furniture assembly.
- Compatible with standard boring machine chucks and adapters - the 10x26mm parallel shank with driving flat fits the toolholding found on most multi-spindle CNC boring centers and panel processing machines, requiring no special adapters for installation.

Frequently Asked Questions
What is the difference between this through-hole dowel drill and a standard blind-hole dowel drill?
This drill uses through-hole geometry, meaning the cutting edges and flute design are optimized for drilling completely through a panel rather than stopping at a flat bottom. The spiral flutes evacuate chips continuously as the bit passes through the full panel thickness, preventing chip packing at the bottom of a closed bore. It is intended specifically for applications where the hole must exit the opposite face of the panel.
What machines is the 10x26mm parallel shank compatible with?
The 10x26mm parallel shank with driving flat fits the standard toolholding found on multi-spindle CNC boring machines, CNC boring centers, and panel processing centers. It can also be used in a boring machine equipped with a compatible adapter or chuck. The length adjusting screw allows precise depth positioning during setup.
What does the PTFE coating on the spiral flutes do during use?
The PTFE coating applied to the spiral portion of the drill body reduces friction and prevents pitch, resin, and glue from adhering to the flutes during boring. This is particularly beneficial when processing chipboard, laminated panels, and MDF, which can release adhesive resins during cutting. Keeping the flutes clean maintains consistent chip flow and helps extend the interval between sharpenings.
How many times can this drill be resharpened?
According to the product data, this drill is rated for through-holes sharpening at a value of 60, indicating the number of sharpenings supported over the tool's service life. The hardmetal (HW) cutting head and precision-ground edges allow repeated resharpening while maintaining bore quality, making this a cost-effective choice for high-volume panel boring operations.
