Product Description
CMT 363.045.12 V-Point Solid Carbide Twist Drill - 4.5mm Left-Hand is a precision-engineered, solid carbide twist drill designed for through-hole drilling on CNC boring machines and multi-spindle boring centers. Built from premium HWM solid carbide material, this 4.5mm left-hand rotation drill delivers consistent, clean bores in panel processing, furniture manufacturing, and wood-based composites. Its V-point 120 deg. sharpening geometry ensures accurate entry and reduced tear-out, making it a reliable choice for high-volume production environments where precision and tool longevity are critical.
Key Features
- V-Point 120 deg. Sharpening - the self-centering point geometry guides the drill accurately into the workpiece, reducing wandering and improving hole positioning for tight-tolerance dowel and joinery applications.
- Premium HWM Solid Carbide Construction - full solid carbide provides exceptional hardness and wear resistance, extending tool life in high-speed production drilling and reducing downtime from frequent bit changes.
- 2 Precision Ground Cutting Edges (Z2) - dual precision-ground flutes deliver balanced cutting action, producing smooth, clean bore walls in panel materials and composite substrates.
- 2 Spiral Flutes - efficient chip evacuation through spiral flute design minimizes heat buildup and clogging during continuous CNC operation, protecting both the tool and the workpiece surface.
- Left-Hand Rotation (LH) - engineered specifically for left-hand spindle positions on multi-spindle boring centers, this drill is compatible with CMT 364 and 365 series adapters for direct integration into production setups.
- Common Shank Design (S=D) - the shank diameter matches the drilling diameter at 4.5mm, allowing direct, secure mounting in CMT 364/365 bushings and adapters without spacers or adapters beyond those specified.
- 28mm Cutting Height - sufficient flute length for through-hole drilling in standard panel thicknesses used in cabinet and furniture production.
Why This Product
- Designed specifically for use with CMT 364 and 365 series adapters, this drill integrates directly into multi-spindle boring center setups without modification, saving setup time and ensuring a precise, secure tool hold.
- The left-hand rotation configuration fills a critical gap in CNC boring machine tooling - matching the correct spindle direction for left-hand positions and ensuring clean, accurate holes rather than tear-out or off-center bores.
- Solid carbide HWM construction delivers the wear resistance needed for demanding production environments - chipboard, MDF, laminates, and hardwood all challenge lesser tooling, and the all-carbide body maintains cutting edge sharpness across extended production runs.
- The 4.5mm (3/16 in.) diameter paired with a 60mm total length is a standard sizing for dowel-hole boring in panel furniture production, making this a practical drop-in replacement or expansion drill for existing CNC boring machine toolsets.

Frequently Asked Questions
What is the difference between left-hand and right-hand twist drills, and why does it matter for CNC boring machines?
Left-hand (LH) twist drills are designed to rotate in the opposite direction from standard right-hand drills. Multi-spindle boring centers typically use a combination of left-hand and right-hand spindles to drill multiple holes simultaneously. Using a drill with the correct rotation for each spindle position is essential for clean, accurate bore entry and proper chip evacuation. The CMT 363.045.12 is specifically designed for left-hand spindle positions.
What adapters are required to use this drill on a CNC boring machine?
This drill is designed for use with CMT 364 and 365 series adapters and bushings. Because the shank diameter equals the drill diameter (S=D at 4.5mm), it mounts directly into those compatible CMT adapter systems without additional hardware beyond the designated 364/365 components.
What does "V-Point 120 deg. sharpening" mean and how does it affect drilling performance?
The V-Point 120 deg. refers to the geometry of the drill tip - the included angle formed between the two cutting edges at the point of the drill. A 120 deg. V-point is a common standard for wood and panel-material drilling. It provides self-centering entry to reduce bit walking, enables clean hole entry with minimal tear-out, and is well-suited to the through-hole drilling applications typical in furniture and panel manufacturing.
Is this drill compatible with materials like MDF, chipboard, and laminates?
Yes. The solid HWM carbide construction and precision-ground dual cutting edges make this drill suitable for demanding panel materials including chipboard, MDF, HDF, plywood, and laminates, as well as solid hardwood and softwood. The carbide material resists the abrasive nature of engineered wood composites far better than high-speed steel tooling, supporting longer service life in production environments.
