Leitz Premium Boring Bit D40xGL54.5 Z2 V2 RH
Premium Boring Bit
High-performance carbide boring bit engineered for precision hole processing in industrial cabinet, millwork, and panel-production environments. Its Z2 cutting geometry and dual V-spur configuration support clean entry, smooth hole walls, and repeatable right-hand boring performance.
Main Product Description
The Leitz Premium Boring Bit L34677 is designed for production-scale cabinetry, millwork, and panel machining where clean, accurately sized holes are required. Its 40 mm cutting diameter and 54.5 mm total length provide a compact, stable geometry for repeatable boring operations.
The Z2 cutting arrangement works with two V-shaped scoring spurs to establish a clean hole perimeter before the central cutting edges remove the core material. This geometry helps reduce entry breakout and supports smooth hole walls in solid wood and composite panel products.
Industrial-grade carbide cutting edges provide wear resistance for high-duty-cycle production. Correct spindle alignment, toolholding pressure, rotation direction, feed settings, and dust extraction help maintain dimensional accuracy and extend useful service life.
Best Fit Applications
Product Highlights
Clean Entry Geometry
Two V-shaped scoring spurs establish the hole perimeter before the main cutting edges remove material.
Balanced Z2 Cutting
The two-tooth arrangement distributes cutting load evenly to support smooth boring and consistent hole quality.
Carbide Wear Resistance
Industrial carbide cutting edges help preserve geometry and dimensional accuracy during repeated production cycles.
Compatibility & Installation Notes
Confirm that the machine spindle, chuck, or boring aggregate accepts the required mounting interface and right-hand rotation. Verify spindle alignment, toolholding pressure, operating speed, feed rate, and drilling depth before production. Inspect the carbide edges and scoring spurs for wear, damage, or resin buildup, and use effective dust extraction during machining.
Maintain Accurate Production Boring
The Leitz Premium Boring Bit L34677 is built for cabinet shops, millwork manufacturers, and panel-processing lines requiring clean, repeatable 40 mm holes. Its 54.5 mm total length, Z2 cutting geometry, V2 scoring-spur arrangement, and right-hand rotation support consistent boring on compatible equipment.
Combining controlled scoring action with carbide wear resistance, this boring bit helps reduce edge breakout, preserve hole-wall quality, and maintain production accuracy across repeated drilling cycles.
