Product Description
CMT 363.030.42 V-Point Solid Carbide Twist Drill - 60 deg. - 1/8 in. x 2-11/64 in. - Left-Hand Rotation is a precision-ground, two-flute twist drill built from solid carbide for through-hole drilling on CNC boring machines and multi-spindle boring centers. Designed for left-hand (LH) rotation, this 3mm diameter drill delivers clean, accurate bores in a wide range of wood-based panel materials - including solid hardwood, MDF, chipboard, and laminated sheet goods - where consistency and tool longevity matter most. The V-Point 120 deg. sharpening geometry centers the drill precisely on entry, reducing wandering and tear-out for production-quality results on every cycle.
Key Features
- Solid Carbide (HWM) Construction - premium hard metal carbide provides exceptional wear resistance, allowing the drill to maintain cutting sharpness through high-volume production runs far longer than standard high-speed steel alternatives.
- V-Point 120 deg. Sharpening Geometry - the V-point tip centers accurately on the workpiece surface, minimizing drill walk and delivering cleaner entry holes in solid wood, MDF, chipboard, plywood, and laminates without pre-marking.
- Left-Hand (LH) Rotation - engineered specifically for LH spindles on CNC boring machines and multi-spindle boring centers, ensuring proper chip evacuation and cutting action for machines configured for left-hand tooling.
- Common Shank Design (S=D) - the shank diameter equals the drill diameter at 3mm, allowing direct compatibility with CMT 364 adapters and 365 bushings for secure, concentric mounting on standard boring machine spindles.
- 2-Flute Configuration - dual cutting edges balance cutting forces evenly and promote efficient chip clearance, reducing heat buildup and extending tool life during continuous production drilling operations.
- Compact, Precise Dimensions (27mm cutting height, 55mm total length) - the optimized length-to-diameter ratio suits tight boring head configurations while providing sufficient flute length for through-hole drilling in common panel thicknesses.
Why This Product
- Solid carbide construction paired with V-Point 120 deg. geometry makes this drill a reliable choice for CNC cabinet and furniture production shops that demand consistent hole quality in hardwood, softwood, MDF, and laminated panels cycle after cycle.
- Left-hand rotation is purpose-built for LH boring machine spindles - using the correct rotation direction ensures proper cutting action and chip flow, preventing workpiece damage and premature tool wear that can result from using wrong-rotation tooling.
- The common shank (S=D) design integrates directly with CMT 364 adapters and 365 bushings, making this drill a natural fit for shops already running CMT boring machine tooling systems without requiring custom adapters or modifications.
- At 3mm diameter with a 27mm cutting height and 55mm total length, this drill is proportioned for the confined spindle spacing typical of multi-spindle boring centers, giving operators a solution that fits where larger or longer drills cannot.

Frequently Asked Questions
What does the left-hand (LH) rotation designation mean, and how do I know if my machine needs it?
Left-hand rotation means the drill cuts when spinning counter-clockwise (when viewed from the shank end). Multi-spindle boring centers often have a combination of right-hand and left-hand spindles to allow simultaneous drilling from both sides or at alternating positions. Check your boring machine's spindle specification or manual to confirm which spindles require LH tooling before installing this drill.
Do I need a special adapter to mount this drill on my boring machine?
Yes. This twist drill uses a common shank design where the shank diameter equals the drill diameter (3mm). It is designed for use with CMT 364 adapters and CMT 365 bushings, which adapt the drill's 3mm shank to standard boring machine spindle collets. Make sure the appropriate adapter and bushing are installed before use.
What is the V-Point 120 deg. sharpening, and why does it matter for wood and panel drilling?
The V-Point 120 deg. designation refers to the geometry of the drill's tip - a sharp, centered point ground to a 120 deg. included angle. This geometry self-centers on the workpiece at the moment of contact, which reduces drill wander on smooth or slick surfaces like laminates and MDF face layers. The result is a cleaner, more accurately positioned entry hole compared to flat-bottom or brad-point geometries when drilling through-holes in panel materials.
Can this drill be used in a handheld drill or router collet?
No. This drill is engineered specifically for CNC boring machines and multi-spindle boring centers. Its left-hand rotation, 3mm common shank, and reliance on CMT 364/365 adapters for proper mounting make it incompatible with handheld drills or standard router collets, which are configured for right-hand rotation tooling and different shank systems.
