Engineered for precise hole enlargement and stable size control, these tools deliver reliable surface quality in CNC machining. Solid carbide bodies and advanced geometries enable steady cutting, predictable wear, and productivity from roughing to finishing—even in difficult materials.
Select the configuration that fits your diameter range, tolerance target, and machine setup.
High rigidity and strong vibration control suit small to medium diameters. They support micron-level accuracy and fine finishes, including high-speed cuts with internal coolant.
Balanced, adjustable cartridges remove stock quickly and allow fast diameter changes. Modular bodies with indexable inserts simplify maintenance and support high-volume production.
Micro-adjust mechanisms set diameter in 1–2 μm steps, achieving IT6–IT7 tolerances and good cylindricity. Use for the final pass when surface integrity and repeatability matter most.
Carbide and steel shanks handle deep bores and small diameters with anti-vibration design. Carbide shanks improve stiffness at long overhangs to reduce chatter.
Complete steps and chamfers in one pass to cut tool changes and cycle time while keeping features concentric.
Paired with dedicated insert grades, these systems balance cost and performance in steels, stainless, cast iron, and high-temperature alloys. Optimized chipbreakers aid chip control and help extend tool life.
Ultra-fine grain carbide combines with application-specific coatings for wear and thermal stability. Options include AlTiN/TiAlN for steels and high-temp alloys, TiSiN for hardened work, DLC or polished edges for aluminum, and diamond for abrasive composites or graphite.
Tools are ground on multi-axis Swiss and German CNC platforms to sub-micron accuracy. Inspection on ZOLLER and PARLEC systems verifies runout ≤ 3 μm and, for fine boring, diameter repeatability within ±2 μm. Depending on setup and material, bores can reach Ra 0.2–0.4 μm.
Match tolerance, material, reach, and machine capability to ensure stable processes and predictable results.
Use rough heads to establish diameter when stock is high. Switch to fine boring with micro-adjust and rigid shanks for IT6–IT7 and premium finishes.
Align coatings and geometry with the workpiece: TiAlN/AlTiN for steels, stainless-optimized chipbreakers, DLC/diamond for nonferrous and abrasives. Ensure effective chip evacuation in deep holes.
Choose HSK/BT/ISO interfaces and high-precision collet or hydraulic chucks to minimize runout and vibration, especially with long overhangs.
Run higher feeds and depths during roughing; finish with light cuts and controlled speeds to hit size and surface targets.
Through-coolant improves chip flow and temperature control, supporting consistent size in long bores and gummy materials.
For steps, counterbores, chamfers, and tapers, tailored designs are available from drawings or samples. Sub-micron grinding, balanced assemblies, and application-specific geometries can reduce passes and cycle time. Pilot batches and measurement reports support validation before scaling.
Produced in our Changzhou facility on Swiss TTB, WALTER Helitronic, DECKEL, and ANCA platforms. ISO 9001 procedures guide production, and each tool is inspected on ZOLLER and PARLEC systems. Documentation such as SGS reports can be provided as required.
Solid carbide typically Ø3–50 mm; rough/fine heads cover Ø20–200 mm+, with 1–2 μm micro-adjust for fine boring.
Standard and extended lengths available; select anti-vibration options beyond 4×D to maintain accuracy and finish.
HSK/BT/ISO shanks; balanced assemblies offered for high-speed spindles (e.g., G2.5 at 20,000 rpm).
Through-tool coolant enhances chip evacuation and thermal stability; external coolant supports general-purpose use.
AlTiN/TiAlN, TiSiN, DLC, and diamond; uncoated polished edges for certain nonferrous applications.
Common uses include engine blocks, transmission housings, aerospace structures, molds, and medical components. Stable performance helps reduce rework and scrap while shortening cycle times in both small batches and mass production.
Send a drawing or sample with material, machine model, clamping method, target tolerance, and expected volume. Our team will recommend geometry, coating, and setup to meet your cycle time and quality goals.
