Product Description
CMT Dowel Drill for Through Holes - 5/32" x 30 x 70mm Right-Hand by CMT is a precision-engineered, carbide-tipped boring tool designed for clean, blowout-free through holes in panel processing and furniture manufacturing. Purpose-built for multi-spindle CNC boring machines, boring centers, and panel processing equipment, this dowel drill drives straight through chipboard, MDF, hardwood, softwood, plywood, and coated laminates with consistent accuracy. The 30mm cutting height accommodates panels up to 30mm thick, while the hardmetal (HW) tipped head and PTFE-coated spiral work together to produce clean bore walls, prevent pitch buildup, and extend tool life across high-volume production runs.
Key Features
- Hardmetal (HW) tipped head with precision-balanced centre point - delivers accurate hole positioning and a clean entry point on every bore, reducing misalignment in dowel joinery and panel assembly.
- 2 precision-ground cutting edges (Z2) - balanced twin-flute geometry produces smooth, consistent bore walls and minimizes vibration, which is critical for tight dowel-joint tolerances in furniture production.
- PTFE-coated spiral portion (orange or black) - the non-stick coating prevents pitch, resin, and glue buildup on the flutes, keeping the tool cutting freely and reducing cleaning downtime between operations.
- Super-strength steel body - a robust steel shank and body resist deflection under high-cycle machine loads, maintaining dimensional accuracy across extended production use.
- 2 spiral flutes designed for through-hole boring - efficient chip evacuation through the full depth of cut prevents chip packing and blowout at the panel exit face, resulting in clean holes on both sides of the workpiece.
- Parallel shank (10 x 26mm) with driving flat and length-adjusting screw - secure, slip-free seating in multi-spindle boring machine chucks with easy depth adjustment for consistent, repeatable results.
- Right-hand (RH) rotation - standard rotation compatible with the vast majority of CNC boring centers and multi-spindle panel processing equipment.
- 70mm overall length with 30mm cutting height - the long-series format reaches through panels up to 30mm thick while keeping the shank fully engaged in the chuck for maximum stability.
Why This Product
- Built for blowout-free through holes - the through-hole geometry, precision-balanced centre point, and twin spiral flutes work together to clear chips efficiently and prevent tear-out at the panel exit face, which is essential for high-quality furniture and cabinet components where both faces are visible.
- PTFE coating reduces maintenance in high-volume runs - the non-stick spiral coating resists pitch and adhesive buildup from coated panels and laminates, meaning fewer tool stoppages for cleaning and more consistent performance across long production shifts.
- Hardmetal (HW) tipped construction for demanding materials - the HW head handles the full range of panel materials including chipboard, MDF, HDF, hardwood, softwood, and laminates, making this a versatile single-tool solution for mixed-material panel shops.
- Parallel shank with driving flat and adjusting screw for reliable machine fitment - the 10 x 26mm shank design locks securely in standard boring machine chucks and allows precise depth setting, reducing setup time and ensuring consistent hole depth across every spindle in a multi-spindle head.

Frequently Asked Questions
What is the maximum panel thickness this dowel drill can bore through?
The cutting height of this drill is 30mm, which means it is designed to bore completely through panels up to 30mm thick in a single pass. The 70mm total length ensures the shank remains fully seated in the machine chuck while the full cutting height engages the workpiece.
What materials can this dowel drill cut through?
The hardmetal (HW) tipped head and precision-ground cutting edges are suited for chipboard, MDF, HDF, hardwood, softwood, plywood, laminates, and coated panels. The PTFE-coated spiral helps prevent pitch and adhesive buildup when processing coated or laminated panels.
What machines accept this dowel drill's shank?
This drill features a 10 x 26mm parallel shank with a driving flat and length-adjusting screw, which is the standard interface for multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines equipped with a compatible adapter or chuck.
Why choose a through-hole dowel drill instead of a blind-hole dowel drill for this application?
Through-hole dowel drills are specifically designed to bore completely through a panel from one face to the other. The 2 spiral flutes on this drill evacuate chips efficiently along the full depth of cut, helping prevent blowout at the exit face. If the application only requires a pocket that does not pass fully through the panel, a blind-hole dowel drill geometry would be the appropriate choice instead.
