Product Description
CMT 375.070.11 4 Flute Dowel Drill for Through Holes - 9/32" x 2-3/4" RH is a precision-engineered through-hole dowel drill from CMT, designed for fast, clean boring in panel processing applications. Built with a 7mm diameter and a 40mm cutting height on a 70mm total-length body, this right-hand rotation drill handles solid wood, chipboard, MDF, HDF, plywood, laminates, and coated panels with consistent accuracy. Its 10x20mm shank makes it compatible with multi-spindle CNC boring machines and panel processing centers, delivering professional-grade results in cabinet making, furniture manufacturing, and woodworking production environments.
Key Features
- Tungsten Carbide (HW) Cutting Material - hard-metal carbide construction maintains a sharp cutting edge through high-volume production runs in abrasive materials like chipboard, MDF, and laminates, reducing tool replacement frequency.
- Through-Hole Geometry with 60 deg. Sharpening Angle - the through-hole point geometry creates clean entry and exit holes on panel faces, minimizing tearout on both sides of the workpiece for a finished appearance without secondary sanding.
- 2-Tooth Configuration on a 4 Flute Profile - the combination of 2 cutting teeth and 4 flutes optimizes chip evacuation during through-hole drilling, reducing heat buildup and producing smooth bore walls in a single pass.
- 40mm Cutting Height - the generous cutting length accommodates panels across a practical range of thicknesses, giving the drill versatility across different panel types in the same production setup.
- 10x20mm Shank - the standardized shank dimensions ensure secure, concentric seating in multi-spindle boring heads and CNC boring centers, supporting accurate hole placement and repeatable results.
- Right-Hand (RH) Rotation - designed for conventional right-hand spindle machines, making this drill a direct-fit replacement or addition to standard CNC and multi-spindle boring equipment without any adapter modification.
- Long Series 70mm Total Length - the extended body length provides additional clearance in multi-spindle head configurations, allowing the drill to reach full cutting depth even when mounted alongside adjacent boring tools.
Why This Product
- The through-hole point geometry with 60 deg. sharpening is purpose-built for panels that require clean bore openings on both faces - ideal for dowel joinery, shelf pin holes, and hardware insertion points where surface quality on exit is critical.
- Hard-metal (HW) carbide construction holds up in abrasive engineered wood products like chipboard and MDF, where high-speed steel tools dull quickly - making this a practical choice for production shops drilling hundreds of holes per shift.
- The 7mm diameter and 10x20mm shank match common multi-spindle boring head specifications, allowing this drill to integrate directly into existing CNC boring centers and panel processing equipment without custom adapters.
- At 70mm total length, this long-series drill provides the reach needed in densely packed boring heads where shorter drills cannot achieve full cutting depth - solving clearance problems common in high-density multi-spindle setups.

Frequently Asked Questions
What is the difference between a through-hole dowel drill and a blind-hole dowel drill?
A through-hole dowel drill, like this CMT 375.070.11, is ground with a geometry that allows the cutting tip to exit the opposite face of the panel cleanly. A blind-hole drill is designed to stop at a precise depth without breaking through. This drill uses a through-hole 60 deg. sharpening angle specifically to produce clean entry and exit openings on both panel faces.
What machines is this 7mm through-hole dowel drill compatible with?
This drill is designed for use in multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines equipped with a compatible adapter or chuck. The 10x20mm shank fits standard boring head configurations used in these machine types.
Why does this drill have 2 teeth if it is described as a 4 flute drill?
The 4 flute design refers to the spiral flute geometry of the body, which promotes efficient chip evacuation and smooth bore walls. The 2 cutting teeth are the actual cutting edges doing the material removal. This combination balances cutting efficiency with chip clearance - particularly important when drilling through panels in a single pass without clogging.
Can this drill be used on laminated and coated panels without damaging the surface?
Yes. The through-hole geometry with the 60 deg. sharpening angle is designed to produce clean entry and exit holes, which is important for laminated and coated panels where surface tearout on either face would be visible and unacceptable. The hard-metal (HW) carbide material also maintains sharpness through the abrasive nature of laminates and coatings.
