Building on the proven PF‑10 profile, PF‑10L Long‑Reach Diamond Precision Files extend to 140 mm overall length with a 70 mm diamond zone, enabling precise work in deep cavities and long bores. The spring‑steel core provides both stiffness and gentle flex, while the tightly bonded diamond layer delivers durable, consistent cutting for deburring, and shaping.

Key Advantages

Extended Reach – 140 mm length easily accesses deep or recessed areas.

Comprehensive Shapes & Grits – Flat, square, round, triangular in #150, #200, #400.

Reinforced Coating – Precision electroplating locks diamonds securely for long‑lasting wear.

Resilient Core – Controlled flex to follow contours and minimize breakage or scratching.

Complete Set – Covering popular sizes and profiles for quick changeovers in mold repair and volume production.

Recommended Materials

Tungsten carbide, hard alloys, ceramics, quartz, glass, tool steel, stainless steel, gemstones, and other hard/brittle substrates.

Typical Applications

Deburring deep holes, slots, and internal corners

Refining gates and runners in injection or die‑casting molds

Polishing deep cavities of components

Finishing narrow features in precision fixtures and jigs
