Original Japan BIG DAISHOWA NBC10-10E Stainless Steel Ultra Precision Collet, Fixed 10mm Shank for High Speed Mold Hardened Steel Machining CNC Tools

Product Overview

The BIG DAISHOWA NBC10-10EAA (short code NBC-10-10E) belongs to the premium NEW BABY (NBC) high-precision collet series developed by BIG DAISHOWA (Japan Daishowa Seiki). It is a fixed single-diameter end mill dedicated collet without clamping tolerance range, exclusively designed for clamping cutting tools with exactly Ø10mm straight shank. Made of anti-rust stainless steel with ultra-precision multi-stage grinding, this AA-grade collet guarantees ultra-low runout of 1μm at collet nose, perfectly matched with MEGA10N / NBS10 NEW BABY tool holders. It is the top choice for high-speed mold finishing, hard steel machining and precision component CNC processing, solving vibration, poor surface finish and fast tool wear problems caused by low-precision standard collets.

Advantages of BIG DAISHOWA NBC10-10E Fixed Diameter Collet

• E-type fixed single diameter design: Only clamps exact Ø10mm shank cutters, eliminates clearance gap between collet and tool shank, achieves far higher rigidity than range-type AA collets, effectively suppress high-speed cutting vibration
• Industry-leading 1μm nose runout accuracy: Significantly improves workpiece surface roughness, extends carbide tool service life by 30%+ compared with ordinary ER collets
• Anti-rust 440 stainless steel substrate: Resists erosion of water-soluble coolant, no rust adhesion after long-term continuous wet machining, stable precision for long service cycle
• Uniform multi-slit elastic structure: Balanced circumferential clamping force, no indentation or damage on polished carbide tool shanks
• Double strict factory inspection process: Every AA-grade NBC collet undergoes two independent precision tests to eliminate defective products, consistent batch dimensional repeatability
• Perfect compatibility with BIG MEGA10N series chucks: Full concentricity matching, no secondary runout loss after assembly, supports ultra-high spindle speed machining up to 45,000 RPM
