HSS 90 Deg Countersink with Universal Shank Product Details (For Magnetic Drills Machine)

1. Product Overview

This HSS 90° Countersink with Universal Shank is a high-performance industrial cutting tool designed for general metal chamfering and countersinking. Made of premium high-speed steel (HSS) with excellent toughness and cutting performance, this 90-degree countersink perfectly matches the standard angle of common countersunk screws. Equipped with a universal shank design, it offers great compatibility with various processing equipment, ideal for daily machining, maintenance work and batch light-duty cutting tasks.

2. Core Product Specifications

Standard working angle:90 degrees, the universal standard angle for metric and imperial countersunk fasteners. This countersink set includes 5 popular large-size specifications: 30mm, 35mm, 40mm, 45mm, 50mm, covering large-diameter hole chamfering and deep countersinking requirements for heavy-duty workpieces. Featured with a universal shank design, each tool can be firmly clamped by most standard drilling and milling equipment without extra adapters, meeting versatile large-scale deburring, chamfering and countersinking demands.

3. Product Material & Structural Advantages

1. Premium HSS Material: Manufactured from high-quality high-speed steel with fine grain structure, the countersink delivers good hardness, exceptional impact resistance and excellent toughness. It is not easy to crack or chip during intermittent cutting, far more durable than ordinary carbon steel cutters, and suitable for processing low and medium hardness metals.

2. 90° Standard Cutting Angle: Precisely milled 90-degree cutting edge ensures flat and smooth countersink surfaces. It perfectly fits standard 90° countersunk head screws, allowing tight and flush assembly without protruding or sinking gaps, guaranteeing neat and professional workpiece finishing.

3. Universal Shank Design: The universal shank features stable clamping performance, strong grip and low vibration during operation. It is universally compatible with Magnetic drills, bench drills, requiring no special adapters for installation, which greatly improves operation convenience and processing efficiency.

4. Product Performance Characteristics

The HSS countersink undergoes fine heat treatment and precise edge polishing, featuring sharp cutting edges, smooth chip removal and low cutting resistance. It can efficiently remove burrs, smooth hole orifices and create standard countersinks. The tool maintains stable cutting performance during long-term use, with high processing consistency and low failure rate, suitable for long-time continuous light-duty processing.

5. Application Scenarios

Widely applicable for large-diameter chamfering, countersinking and heavy deburring on carbon steel, aluminum alloy, copper, iron, plastic and other common materials. Ideal for heavy hardware processing, large mechanical assembly, structural part machining, workshop overhaul and custom industrial processing scenarios. It is a practical essential tool for large-size workpiece finishing and industrial batch processing.
