Product Description
CMT 310.051.11 Dowel Drill - 13/64" x 1 1/16" x 2 17/64" RH is a precision carbide-tipped boring tool engineered for clean, flat-bottom blind holes in panel processing, furniture manufacturing, and cabinetry applications. Built on a two-flute, right-hand rotation design, this short-series dowel drill delivers fast chip evacuation and accurate bore geometry in solid wood, chipboard, MDF, HDF, laminates, and coated panels - making it a reliable choice for both CNC boring centers and multi-spindle boring machines alike.
Key Features
- Tungsten Carbide (HW) Cutting Material - hard carbide cutting edges maintain sharpness longer than standard high-speed steel, reducing tool changes and keeping production running with consistent bore quality.
- Two-Flute Design with 2 Precision-Ground Spurs - dual cutting edges produce clean bore walls and flat-bottom holes with minimal tearout, so panel faces and veneers stay intact on entry and exit.
- Negatively Ground Spurs - the negative grind geometry scores the material fibers cleanly before the main cutting action, preventing chip-out on coated panels, laminates, and hardwood veneers where surface quality matters most.
- Short-Series Length (57.5mm total length) - the compact 57.5mm body reduces runout and vibration at high spindle speeds, improving bore accuracy and extending bearing life in multi-spindle boring heads.
- 10x27mm Parallel Shank - the standardized parallel shank with driving flat ensures positive, slip-free seating in boring machine chucks and adapters, eliminating tool pull-out during high-feed-rate production runs.
- Right-Hand (RH) Rotation - matches the standard spindle direction of the vast majority of CNC boring centers and panel processing machines, allowing direct installation without special adapters.
- 5.1mm Cutting Diameter - precisely sized for standard dowel bore applications, delivering hole diameters that accept common joinery dowels with the tight tolerance fits required for strong, square furniture assemblies.
- 27mm Cutting Height - sufficient cutting depth for blind dowel holes in panel work, so joints are strong and fully supported without breaking through the opposite face.
Why This Product
- The negatively ground spur geometry and carbide (HW) cutting material work together to produce chip-free bore entries in laminated, coated, and veneered panels - protecting finished surfaces in high-value cabinetry and furniture production.
- At just 57.5mm in total length, this short-series drill fits tightly spaced spindle clusters in multi-spindle CNC boring machines without interference, making it a practical drop-in solution for panel line applications.
- The 10x27mm parallel shank with driving flat is a widely adopted standard in boring machine tooling, so this drill integrates directly into existing setups without requiring special collets or custom adapters.
- With a 5.1mm diameter and 27mm cutting height, this dowel drill is sized to hit the critical bore dimensions that joinery dowels demand - meaning tighter-fitting, more structurally sound furniture joints right out of the machine.

Frequently Asked Questions
What shank size does this dowel drill use, and will it fit my boring machine?
This drill uses a 10x27mm parallel shank with a driving flat - a standard configuration for industrial boring machines, CNC boring centers, and panel processing equipment. It seats directly in chucks or adapters designed for 10mm parallel shanks. If your machine uses this shank standard, no additional adapter is required.
What is the difference between a right-hand and left-hand dowel drill, and why does it matter?
Right-hand (RH) rotation means the drill cuts when the spindle turns clockwise when viewed from the operator's side. This is the standard rotation direction for the majority of CNC boring centers and multi-spindle boring machines. This CMT dowel drill is designed for RH rotation - always verify your machine's spindle direction matches before installation to ensure proper cutting action and avoid tool damage.
What does "negatively ground spurs" mean, and why is it important for panel work?
Negatively ground spurs have a geometry that scores and severs the material's surface fibers cleanly before the main cutting body removes the core. This pre-scoring action is especially valuable when boring into laminates, coated panels, and veneered surfaces, where clean entry and exit edges are critical to finished-part quality. It reduces or eliminates chip-out that can ruin a visible face.
What materials can this dowel drill bore into?
This short-series dowel drill is suited for blind hole boring in chipboard, MDF, HDF, solid hardwood, softwood, plywood, laminates, and coated panels. The carbide (HW) cutting material handles the abrasive nature of engineered wood products like MDF and chipboard, which wear standard high-speed steel tools quickly.
