Product Description
CMT Dowel Drill for Through Hole - 5 x 27 x 57.5mm, Right-Hand Rotation is a solid carbide boring bit engineered for clean, precise through-hole drilling in hardwood, MDF, particle board, veneered panels, and other demanding composite materials. Built entirely from premium quality super micrograin carbide, this right-hand rotation dowel drill delivers the consistent bore quality required in high-speed industrial boring units and CNC router applications, making it a reliable choice for furniture manufacturing, panel processing, and dowel connection work where exit hole quality is critical.
Key Features
- Solid Super Micrograin Carbide Construction (HW) - the entire tool is machined from premium quality super micrograin carbide, providing an almost infinite number of resharpenings and extra safety compared to carbide-tipped designs where the tip can separate from the body.
- Extreme Sharpening Rating - the tool is rated for extreme resharpening capability, meaning operators can restore the cutting edge repeatedly, reducing total cost of ownership over the tool's service life.
- Curved, Negatively Ground Spurs at the Tip - this unique tip geometry produces exceptionally clear bores with no rough edges, delivering smooth, clean hole walls critical for tight-fitting dowel joints and veneered surfaces.
- Centre Point Balanced Design - the precision balanced centre point keeps the drill on-target from the moment of contact, reducing wander and improving bore accuracy across repetitive production runs.
- Plunge Edge Running to Centre - the cutting edge extends all the way to the centre of the bit, reducing drilling resistance and increasing production speed, which translates to higher throughput on automated boring equipment.
- 2 Precision Ground Cutting Edges (Z2) with 2 Spiral Flutes - dual cutting edges and spiral flutes work together to clear chips efficiently and maintain bore consistency, extending intervals between sharpenings.
- Cylindrical Head Larger Than Traditional Tips - the oversized cylindrical head is highly resistant to prolonged use, maintaining geometry longer under the demands of continuous production environments.
- Parallel Shank 10 x 27mm with Driving Flat and Adjustable Screw Length - the standardized shank format ensures compatibility with multi-spindle CNC boring machines and panel boring centers, and the driving flat prevents slippage under torque.
- Right-Hand Rotation - configured for standard RH spindle direction found on the vast majority of industrial boring units and CNC machining centers, allowing direct drop-in use without spindle reconfiguration.
- Ideal for Hardwood and Difficult Composites - performs on particle boards, MDF, and veneered wood where surface quality at the exit hole is essential - the through-hole geometry prevents blowout on exit.
Why This Product
- Clean exit holes without blowout - the curved, negatively ground spur geometry and through-hole bit design work together to produce exit holes as clean as entry holes, which is essential when both faces of a panel are visible in finished furniture.
- Designed for high-volume production environments - the combination of solid carbide construction, extreme resharpening capacity, and reduced drilling resistance makes this bit suited for CNC boring centers and multi-spindle machines running continuous production cycles.
- Works across a broad range of panel materials - from solid hardwood to MDF, particle board, and veneered panels, a single bit handles the variety of materials common in furniture and cabinet manufacturing without switching tools.
- Solid carbide body adds a safety advantage - because the tool is a single unit of carbide rather than a brazed tip, there is no joint that can fail under heat or vibration, providing an added margin of safety in high-speed spindle applications.

Frequently Asked Questions
What is the difference between a through-hole dowel drill and a blind-hole dowel drill?
A through-hole dowel drill is designed to bore completely through the workpiece and exit cleanly on the opposite face. The tip geometry - including the curved, negatively ground spurs on this bit - is specifically configured to prevent blowout at the exit hole, producing a clean bore on both faces. A blind-hole drill, by contrast, is designed to stop at a set depth without exiting the material.
What machines is this dowel drill compatible with?
This bit features a parallel shank measuring 10 x 27mm with a driving flat and adjustable screw length, making it compatible with multi-spindle CNC boring machines, CNC boring centers, and panel processing centers that accept this shank format. It is also suited for high-speed boring units.
What materials can this bit drill through?
The solid super micrograin carbide construction makes this bit well suited for hardwood and difficult composites including particle boards, MDF, and veneered wood. The precision ground cutting edges and negatively ground spurs maintain clean bore walls across all of these material types.
How does the solid carbide construction affect resharpening?
Because the bit is a single solid unit of super micrograin carbide rather than a carbide tip brazed onto a steel body, it can be resharpened an almost infinite number of times according to the product data. The extreme sharpening rating also means the plunge edge and spurs hold their geometry longer between sharpenings, reducing downtime in production environments.
