Product Description
CMT Four Flute Dowel Drill 5 x 65 x 105mm Left-Hand (LH) by CMT is a precision-engineered boring tool built for clean, accurate dowel holes in furniture manufacturing, cabinet making, and panel processing. With a 5mm diameter, 65mm cutting height, and 105mm overall length, this extra-long left-hand rotation drill is designed for very deep blind holes in solid wood, chipboard, MDF, and laminated panels on multi-spindle CNC boring centers and large panel processing equipment. The combination of a tungsten carbide (HW) cutting head, four spiral flutes, and negatively ground spurs makes it a reliable choice for high-volume production environments where hole quality and tool longevity are critical.
Key Features
- HW (Tungsten Carbide) Cutting Head with Precision Balanced Centre Point - delivers accurate hole entry and consistent bore depth, reducing wander and improving repeatability across high-volume drilling cycles in CNC production environments.
- 2 Precision-Ground Cutting Edges (Z2) - provides sharp, efficient material removal through solid wood, chipboard, MDF, and laminates, producing flat-bottom holes suited for dowel joinery.
- 2 Negatively Ground Spurs (V2) - scores the material cleanly before the cutting edges engage, preventing tearout and surface chipping on coated panels and laminates for a clean bore wall finish.
- 4 Spiral Flutes - efficiently evacuate chips and dust from deep blind holes, reducing heat buildup and keeping the cutting zone clear during extended boring cycles.
- Super-Strength Steel Body with PTFE Coating - the cutter portion is coated with black or orange PTFE, which resists pitch and glue buildup during boring, extending tool life and maintaining cutting performance over time.
- Parallel Shank 10x30mm with Driving Flat and Length Adjusting - the driving flat ensures positive engagement in the spindle chuck, preventing slippage, while the length-adjusting feature allows precise depth setting on CNC boring centers.
- Left-Hand (LH) Rotation - engineered for left-hand spindle positions on multi-spindle CNC boring machines and panel processing centers, ensuring proper cutting geometry and hole quality on LH spindle stations.
- Extra-Long 105mm Overall Length - extends reach into deep setups on large boring centers, enabling very deep blind holes that shorter dowel drills cannot achieve in a single pass.
Why This Product
- The 65mm cutting height paired with a 105mm overall length makes this drill the right choice when production setups require very deep blind holes that standard-length dowel drills cannot reach, such as deep-panel applications on large CNC boring centers.
- The negatively ground spurs combined with a precision balanced centre point work together to produce clean, tearout-free holes in laminates and coated panels - critical in furniture and cabinet manufacturing where surface finish quality is non-negotiable.
- Left-hand rotation is a factory-specified design feature, not an adaptation, meaning this drill delivers correct cutting geometry specifically at LH spindle positions on multi-spindle machines without requiring additional tooling modifications.
- The PTFE-coated cutter portion actively resists pitch and glue accumulation during boring operations, helping maintain cut quality and reducing the frequency of tool cleaning or replacement in production environments.

Frequently Asked Questions
What machines is this dowel drill compatible with?
This drill is designed for use on multi-spindle CNC boring centers, panel processing centers, and large CNC boring machines equipped with left-hand (LH) spindle positions. The 10x30mm parallel shank with driving flat is the standard interface for these machine types.
Why are there four flutes on a dowel drill?
Four spiral flutes provide enhanced chip and dust evacuation from deep blind holes compared to two-flute designs. This helps clear the bore during extended cutting cycles, reduces heat buildup, and maintains cleaner hole geometry - particularly important when drilling to the full 65mm cutting depth.
What is the purpose of the negatively ground spurs on this drill?
The 2 negatively ground spurs score the perimeter of the hole before the cutting edges remove material. This scribing action severs wood fibers cleanly at the bore edge, preventing chipping, splintering, or tearout on the panel surface - which is especially important when drilling laminates and coated panels in furniture production.
What does the PTFE coating on the cutter portion do?
The black or orange PTFE coating applied to the cutter portion of this drill resists the adhesion of pitch, resin, and glue to the tool surface during boring. This helps the cutting edges remain clean and sharp for longer periods in production use, reducing the need for frequent tool cleaning or early replacement.
