Aluminum Cut SA SC SD SF Shape Carbide Rotary File

Sturdy and Wear Resistance : These die grinder drill bits are made of tungsten carbide steel, which is highly wear-resistant. Even when grinding metals such as aluminum and copper, the service life is
Carbide Burr with Double-Cut Design : These carbide rotary burrs adopt a cross-line design, which has the characteristics of rapid chip evacuation, can improve work efficiency and shorten cutting time
Widely Used : such as engraving, carving, polishing, deburring, grinding, cutting, chamfering, milling, cleaning, transplanting.

描述

Product Overview

The Aluminum Cut C-Type (Cylindrical Ball Nose) rotary file is specifically engineered for rapid material removal on non-ferrous metals. Unlike standard double-cut burrs that quickly clog when used on soft materials, our Aluminum Cut features extra-wide, deep flutes. This ensures that chips are ejected instantly, keeping the tool cool and sharp for a flawless finish on aluminum, brass, and plastics.

Technical Properties

Material: Premium Tungsten Carbide (YG8 / K30)
Hardness: 90-92HRA
Heat Resistance: Maintains cutting edge up to 800℃
Max Speed (RPM): 3mm Dia: ~60,000 RPM

6mm Dia: ~45,000 RPM
12mm Dia: ~25,000 RPM

Primary Applications

Materials: Aluminum, Aluminum Alloys, Brass, Copper, Soft Magnesium, Zinc, and Hard Plastics.
Industries: Automotive porting, aerospace fabrication, foundry work, and custom metal sculpture.
Operations: Deburring, edge breaking, contouring, and internal radius grinding.

Shape Classification (International Standards)

These codes identify the head shape of the rotary file.

Shape Code	Shape Name	Common Application
Type A	Cylindrical (Plain End)	Surface milling, edge leveling
Type B	Cylindrical (End Cut)	Peripheral and end milling
Type C	Cylindrical Ball Nose	Contouring and radius milling
Type D	Ball / Spherical	Hole enlarging, rounding, concave work
Type E	Oval / Egg	Contoured deburring, rounding edges
Type F	Tree (Radius End)	Rounding narrow contours, internal milling
Type G	Tree (Pointed End)	Reaching into tight, pointed angles
Type H	Flame Shape	Universal contouring and blending
Type L	Taper (Radius End)	Difficult-to-reach areas and radii
Type M	Conical (Pointed End)	Acute angles and narrow deburring

Common Dimensional Specifications

These are the industry-standard sizes for 6mm (1/4") and 3mm (1/8") shank series.
