Product Overview

The XSHB1606 Boring Toolholder with SCPR6 Boring Bit is an integrated precision set engineered for seamless compatibility and high-accuracy micro-hole boring in CNC machining. This pre-matched combination eliminates the need for time-consuming toolholder-bit calibration, directly delivering consistent performance for industries like electronics, medical device manufacturing, and aerospace.

The set leverages the strengths of each component: the XSHB1606 toolholder (rear chamfered, 16mm shank compatibility, H7 inner bore tolerance) ensures stable clamping, while the SCPR6 boring bit (optimized for micro-boring, R0.2 nose radius) delivers smooth cuts. Together, they form a reliable solution for 3-10mm diameter hole machining with runout tolerance ≤0.003mm.

Application Scenarios
  • CNC Machining Centers: Ideal for batch production of small precision parts, reducing tool changeover time by 30%.
  • Micro-Hole Boring in Electronics: Perfect for 4-8mm diameter holes in PCB heat sinks, smartphone midframes, and semiconductor packaging.
  • Medical Device Manufacturing: Suitable for precision holes in titanium surgical tools and PEEK implant housings.
  • Aerospace Miniature Components: Processes lightweight alloy parts where hole concentricity is critical.

Core Advantages
  • Perfect Compatibility: Factory-matched components ensure concentricity ≤0.003mm with no on-site adjustment needed.
  • Rear Chamfered Design: 45° rear chamfer guides bits smoothly into the holder, reducing shank wear by 40%.
  • Dual Precision: SCPR6 bit features a sharp cutting edge ground to ±0.001mm tolerance for superior surface finishes.
  • Broad Compatibility: Works with major CNC brands (Fanuc, Siemens, Mitsubishi) and standard ER32 collets.
  • Durable Coating: TiAlN coating enhances heat resistance up to 600°C for extended tool life.

Frequently Asked Questions
What materials can the SCPR6 boring bit process?
It is designed for high-efficiency machining of carbon steel, alloy steel, cast iron, and non-ferrous metals like aluminum and brass, particularly in micro-hole applications.
How does the pre-calibration benefit my production?
The XSHB1606 and SCPR6 are factory-matched to a concentricity of ≤0.003mm. This eliminates manual setup errors, reducing scrap rates by approximately 25%.
What is the advantage of the TiAlN coating?
The TiAlN coating provides excellent heat resistance up to 600°C and superior wear resistance, allowing for higher cutting speeds (up to 80 m/min) and longer tool life.
Can I request non-standard customized tools?
Yes, we provide non-standard customized services for different hardness and geometric requirements based on specific client machining needs.
What are the delivery terms and options?
We support FOB, CIF, EXW, and Express Delivery. Standard specifications are usually in stock and can be delivered within 24 hours of order confirmation.
Is there a warranty on these precision tools?
Yes, we provide a 12-month warranty covering manufacturing defects to ensure reliable performance in your CNC machining operations.
