CMT Two Flute Dowel Drill for Through Holes - 10x44x77mm Left-Hand Rotation is a precision-engineered, carbide-tipped boring tool designed for clean, accurate through-hole drilling in panel processing and furniture manufacturing applications. Built around a super-strength steel body with a tungsten carbide (HW) cutting head, this left-hand (LH) rotation drill delivers consistently smooth bore walls and reliable dowel-joint alignment in solid wood, chipboard, MDF, laminates, and coated panels. The PTFE-coated spiral flutes and precision-balanced centre point make this tool a dependable choice for multi-spindle CNC boring machines and panel processing centers that demand tight tolerances and high-volume throughput.

Key Features

• HW (Tungsten Carbide) Cutting Head - hard carbide material maintains a sharp cutting edge far longer than standard high-speed steel, reducing downtime for tool changes in production environments.
• 2 Precision-Ground Cutting Edges (Z2) - two symmetrically ground flutes produce balanced cutting forces that minimize vibration, resulting in cleaner hole walls and more consistent dowel-joint fit.
• PTFE-Coated Spiral Flutes - the orange or black PTFE coating prevents pitch and adhesive buildup on the spiral portion, keeping the tool running smoothly and extending its usable service life.
• Precision-Balanced Centre Point - centres the drill accurately at entry, eliminating wander and ensuring each through-hole lands exactly where needed for reliable dowel alignment.
• Parallel Shank with Driving Flat and Length-Adjusting Screw (10x26mm) - the flat and screw combination locks the drill securely in the boring spindle and allows precise depth setting without requiring additional tooling.
• Left-Hand (LH) Rotation - matched to left-hand spindle positions on multi-spindle boring machines, ensuring correct chip evacuation direction and proper engagement for the designated spindle side.
• 44mm Cutting Height in a 77mm Overall Length - the extended cutting length accommodates through-hole drilling in thick panels where a standard-length drill would fall short.
• Super-Strength Steel Body - the steel shank and body resist flex under load, maintaining concentricity and drill geometry even during continuous production runs.

Why This Product

• The 44mm cutting height paired with a 77mm total length makes this drill specifically suited for through-hole applications in thick panels - situations where shorter dowel drills simply cannot reach through in a single pass.
• The combination of a carbide (HW) head and PTFE-coated flutes addresses two of the most common production pain points at once: rapid edge wear and resin/glue fouling of the spiral, both of which slow down high-volume furniture and panel lines.
• Left-hand rotation is not a universal specification - selecting the correctly handed drill for the corresponding spindle position is essential for chip flow, tool engagement, and bore quality. This drill is purpose-built for LH spindle positions.
• The precision-balanced centre point and two precision-ground cutting edges work together to produce straight, burr-free through-holes that seat dowels accurately - critical for flat-pack furniture panels and joinery work where misaligned holes cause assembly failures.
