MTR Rainbow Coated Boring Bar for Steel Small Diameter CNC Boring Tools Precision Machining Swiss Type Lathe Turning Tool Silent

Micro boring tools: one-piece tungsten carbide tools for Swiss-type lathes, covering bore diameters 0.5-12 mm in stainless steel, steel, aluminum and more.

Fully ground on Vollmer 5-axis grinders, polished and passivated - hard, chipping-resistant, burr-free edges with long life.

Edge passes center with micro-ground R corners (R0.05-0.4): low cutting force, high-gloss, burr-free holes, stable on stainless steel.

New flute design removes chips fast; angled edge dampens vibration for smooth micro boring.

Flat anti-vibration shank - mount with SHB holder, never use ER collet.

Full range MTR0.5-MTR12.0: single/double end, straight or extended shanks, 50-100 mm lengths; custom sizes on request.

Every piece inspected before shipment; in-stock fast dispatch.

YOGOU (Zhongshan) Precision Cutting Tools Co., Ltd., 20+ years in high-end precision tooling. Positioning: Micro Precision. Made To Measure. Philosophy: technology-driven innovation, quality-built trust.

Every tool is engineered from real shop-floor conditions - micro bores no standard tool can reach, long overhangs that deflect and chatter, stainless steels that work-harden and weld to the edge, and special geometries with no standard tooling available. We deliver international-class performance at an accessible price.

Factory: 7,000 sqm base, 100+ international CNC grinding machines, 95% automation. Design, precision grinding, coating and full-chain inspection fully in-house - micron-level tolerance, stable volume production of tools down to 1.0 mm, no outsourcing variability.

Quality: five inspection gates - incoming, in-process, pre-coating, post-coating, final - with full traceability from rod to shipment. ISO 9001 certified; national high-tech enterprise; invention, utility-model and design patents.

R&D & custom: engineering partnerships with universities and research institutes; drawing-to-delivery non-standard tooling; OEM/ODM; application engineering and tool-selection support. We sell machining solutions, not just tools.

Range: solid carbide rod tools, indexable inserts, exchangeable modular tools and custom tools. Boring system covers the complete internal sequence - boring, profile turning, grooving, threading - for bores from 1.0 mm, in standard and SSS stainless grades; thread mills across 7 standards, M1.0-M24.

Applications: aerospace, mold & die, EV automotive, 3C electronics. Markets: 50+ countries across Europe, the Americas, Southeast Asia and the Middle East; 500+ distributors and OEM customers.

Delivery: in-stock tools ship within 48 hours; custom tools within 14 days; small batches welcome.

Can you make custom tools to my drawing?

Yes. Send us your component drawing or sample, and our engineers respond with a machining proposal - from design and trial cutting to delivery. Custom tools are typically delivered within 14 days.

What is your minimum order quantity (MOQ)?

Small batches are welcome. We support flexible order sizes from trial quantities to volume production, with in-stock tools shipped within 48 hours.

Are left-hand versions available?

Yes. Most series offer full left-hand variants (e.g. MFR/MFL, MZR/MZL, MGR/MGL, MAR/MAL, MVR/MVL, MXR/MXL, MDR/MDL) to suit any spindle direction.
