Solid Carbide DIN335C Countersink 6PCS Product Details

1. Product Overview

This Solid Carbide DIN335C Countersink 6PCS with TiAlN Coating is an industrial-grade one-piece carbide countersink set consisting of six pieces. Manufactured in strict accordance with the German DIN335C industrial standard and equipped with a high-performance TiAlN (Titanium Aluminum Nitride) coating, this set covers six commonly used standard sizes. It is a universal and high-efficiency cutting tool for precision metal chamfering and countersinking, widely applied in mechanical processing, mold manufacturing, and precision hardware processing industries.

2. Core Product Specifications

The countersink set includes six universal bore sizes to fully meet conventional countersinking processing requirements. The specific dimensions are as follows: 6.3mm, 8.3mm, 10.4mm, 12.4mm, 16.5mm, 20.5mm. The reasonably arranged sizes cater to countersinking, chamfering and deburring processing from small precision workpieces to large hardware accessories.

3. Product Material & Coating Advantages

1. Solid Carbide Material: The cutter body is integrally formed of high-density carbide without splicing gaps. It features high overall hardness, excellent rigidity, superior wear resistance and chipping resistance. Compared with high-speed steel countersinks, its service life is greatly extended. It supports continuous processing of hard metals such as stainless steel, carbon steel, alloy steel and cast iron with no easy deformation or abrasion.

2. TiAlN Coating Technology: The tool surface adopts high-end multi-layer composite TiAlN coating, which delivers outstanding high-temperature resistance, oxidation resistance and low friction performance. It accelerates heat dissipation and smooth chip removal during processing, effectively reducing tool wear and improving the surface finish of finished workpieces. It is suitable for dry cutting and high-speed cutting conditions, greatly boosting processing efficiency and machining accuracy.

4. Product Implementation Standard

Produced in full compliance with the German DIN335C standard, the countersinks feature precise cutting edge angles, high concentricity and regular countersink forming. The processed workpieces have flat and uniform countersinks without burrs or edge chipping, perfectly matching the assembly requirements of standard countersunk head screws and bolts with strong universality and compatibility.

5. Application Scenarios

Widely used in precision mold processing, hardware machinery manufacturing, auto parts processing, sheet metal processing, fixture production and other fields. It is mainly used for hole edge chamfering, screw countersinking, burr removal and workpiece trimming of metal workpieces, adapting to mass precision processing and daily maintenance processing conditions.

6. Product Features

Complete set combination covering full-range conventional processing specifications; integrated solid carbide cutter body with high strength and durability; precisely polished cutting edges for high machining accuracy; wear-resistant and high-temperature-resistant TiAlN coating suitable for high-speed processing; standard DIN335C dimensions with strong universality, compatible with various processing equipment including bench drills, machining centers and electric hand drills.
