Product Description
CMT 363.035.12 V-Point Solid Carbide Twist Drill - 120 deg. Sharpening, 3.5mm, Left-Hand Rotation is a precision-engineered, solid carbide boring drill designed for through-hole drilling on CNC boring machines and multi-spindle boring centers. Built from premium HWM solid carbide, this left-hand (LH) twist drill delivers outstanding wear resistance and consistent hole quality in panel processing, furniture manufacturing, and dowel-joint production. The 120 deg. V-point geometry produces clean, accurate entry points in a wide range of wood-based sheet materials, making it a dependable choice for high-volume production environments.
Key Features
- Solid Carbide (HWM) Construction - premium solid carbide material provides exceptional hardness and wear resistance, extending tool life in demanding, high-speed production drilling applications.
- V-Point 120 deg. Sharpening - the V-point tip geometry delivers a centered, controlled entry into the workpiece, reducing tear-out and improving hole accuracy for dowel connections and panel joinery.
- 2 Precision Ground Cutting Edges (Z2) - dual precision-ground edges ensure a balanced cutting action, producing smooth, consistent bores with minimal vibration during CNC boring operations.
- 2 Spiral Flutes - twin spiral flutes efficiently evacuate chips away from the cutting zone, helping maintain a clean bore and reducing the risk of clogging during through-hole drilling.
- Common Shank Design (S=D, 3.5mm) - shank diameter equals drill diameter, enabling direct, secure seating in CMT 364/365 adapters and boring machine spindle bushings without additional tooling adapters.
- Left-Hand (LH) Rotation - specifically engineered for left-hand spindle positions on multi-spindle CNC boring centers, ensuring correct cutting direction and clean hole formation on the appropriate machine spindles.
- Compatible with CMT 364/365 Systems - designed for use with CMT 364 and 365 adapter systems, making it a direct-fit solution for configured boring machine setups already using CMT tooling infrastructure.
Why This Product
- If your CNC boring center includes left-hand spindles, this LH-rotation, 3.5mm solid carbide drill is the correct tooling choice - using a right-hand drill on a left-hand spindle produces a poor-quality bore, and this drill eliminates that problem by design.
- The V-point 120 deg. sharpening geometry makes this drill well suited for through-hole drilling in chipboard, MDF, plywood, and laminates - materials common in furniture and cabinet panel production where clean entry and exit holes are critical for dowel-joint integrity.
- The HWM solid carbide construction resists wear far more effectively than high-speed steel alternatives, meaning fewer tool changes, more consistent bore diameters over long production runs, and lower overall tooling cost per hole.
- The common shank (S=D) design simplifies setup on multi-spindle boring centers equipped with CMT 364/365 adapters - the 3.5mm shank seats directly into the adapter without secondary bushings or reducers, saving changeover time.

Frequently Asked Questions
What is the difference between LH (left-hand) and RH (right-hand) twist drills, and how do I know which one I need?
Left-hand (LH) twist drills rotate in the opposite direction from standard right-hand drills. Multi-spindle CNC boring centers typically have both left-hand and right-hand spindles arranged across the boring head. You must match the drill rotation to the spindle rotation - using an LH drill on an LH spindle ensures correct cutting direction, clean hole formation, and proper chip evacuation. Check your machine's spindle configuration to confirm which positions require LH tooling.
What does "V-Point 120 deg. sharpening" mean, and why does it matter for panel drilling?
The V-point 120 deg. refers to the included angle at the tip of the drill. This geometry creates a centered, self-locating point that guides the drill accurately into the workpiece surface before the full cutting diameter engages. For panel materials like MDF, chipboard, plywood, and laminates, this tip design helps minimize surface tear-out at the entry point and produces a cleaner, more precise bore - which is especially important for dowel holes that require tight positional accuracy.
Does this drill require a special adapter to mount on a CNC boring machine?
Yes. This twist drill is designed for use with CMT 364 or 365 adapter systems. The common shank design (S=D) means the 3.5mm shank diameter matches the 3.5mm drilling diameter exactly, and the drill seats directly and securely into those adapters without additional reduction bushings. If your boring center is already configured with CMT 364/365 adapters, this drill is a direct-fit replacement.
What materials is this drill rated for?
This solid carbide twist drill is suited for through-hole drilling in wood-based panel materials including solid hardwood, softwood, chipboard, MDF, HDF, plywood, and laminates. The HWM solid carbide construction provides the hardness and wear resistance needed to maintain consistent bore diameters across these materials in high-volume production settings.
