Micro Precision Needle File Master Set (6 pieces)

Description

TOTAL 6 Pcs file set THT91462

TOTAL THT91462 is an industrial-grade, 6-piece micro needle filing system engineered to execute fine deburring, precise keyway dressing, intricate die-stamping overhauls, mold clearing, and detailed metal sculpting. Forged from high-tempered, premium tool steel, this ultra-slim set features six distinct geometric profiles—Flat, Round, Half-Round, Square, Triangle, and Knife—with a 3mm barrel diameter and 140mm total length. Fitted with specialized two-color comfort grip handles, this precision kit gives technical crews absolute tactile control over delicate mechanical fitments and tight clearance adjustments.

High-Carbon Metallurgy & Precision-Cut Grating

• Toughened Carbon Tool Steel Matrix: Every micro file in this 6-piece network is precision-machined from high-carbon tool steel, heat-treated to an advanced hardness profile. This industrial metallurgy ensures the abrasive teeth maintain sharp, crisp edges when cutting into hard steel, bronze, aluminum, dense polymers, and engineering resins
• Uniform Second-Cut Tooth Geometry: Features an automated, high-density tooth-cutting pattern across all faces. This specific abrasive density delivers a perfect balance of swift stock removal and a clean, scratch-free surface finish, preventing the file from skating over hard surfaces
• Tapered Precision Tips: Ground to sharp, micro-profiled noses to let operators work inside deep, blind recesses and tiny drill holes where traditional deburring gear cannot fit

Two-Color Comfort Handles & Tactical Grip Response

• Ergonomic Dual-Material Mini Grips: Unlike low-grade needle files with bare metal tangs that cause finger cramping, the THT91462 is fitted with full-scale, rubberized two-color comfort handles. These anti-slip sleeves absorb finger pressure and repel oil, grease, and shop chemicals
• High-Friction Radial Fluting: The handle body features molded thumb notches and micro-textures that maximize tactile feedback, giving technicians the precision needed to execute microscopic material removal with zero slipping

Comprehensive Profile Breakdown:

1. Flat Needle File: Rectangular - Dressing slots, flattening high spots on keys, squaring up internal steps
2. Round Needle File: Circular (Tapered) - Enlarging miniature drill holes, deburring internal radii, profiling concave paths
3. Half-Round Needle File: Semi-Circular - Dual-purpose dressing; flat side for plane faces, curved side for large inner curves
4. Square Needle File: Square - Cleaning out 90° internal angles, slots, splines, and micro-keyways
5. Triangle Needle File: Equilateral Triangle - Filing acute internal angles, clearing thread pitches, and cleaning gear tooth profiles
6. Knife Needle File: Acute Wedge - Slipping into ultra-narrow slots, slitting operations, and acute wedge deburring
