1/4-Inch Angle Air Die Grinder Kit with 22-Piece 2-Inch Disc Set – Polished Pneumatic Grinder

Overview

Meet a compact, high-power tool built for precision grinding in tight spaces. The 1/4-inch angle air die grinder blends a robust pneumatic motor with a lightweight, ergonomic body to support metal, plastic, stone, and wood finishing tasks with confidence. This kit comes with a comprehensive 22-piece set of 2-inch discs, designed to cover a range of grinding, polishing, and cleaning needs right out of the box.

Tailored control for diverse tasks

Use the stepless speed control to dial in the exact pace for each job. For delicate edges, a slower setting helps manage heat and achieve smoother finishes; for aggressive material removal, a faster setting can accelerate work while maintaining control.

• Adjustable speeds help reduce heat buildup on sensitive materials.
• Low vibration supports steadier finishing and less fatigue during long sessions.

Durable, precise chuck and bearings

The industrial grade 1/4 inch chuck provides high wear resistance, low vibration, and excellent concentricity. A stable operation reduces drift and heat during extended use, while the hardened collet resists deformation under impact.

• Carburized 1/4 inch collet maintains holding power and tolerances.
• High temperature processing and CNC lathe precision contribute to reliable performance.

Air efficiency and safety

Air inlet filtration helps keep impurities out of your tool, while an annular exhaust design directs spent air away from your work surface. The plate type start-stop switch adds safety during operation for smoother, more controlled starts and stops.

• Filtration improves air quality for cleaner finishes.
• Safe pressure plate start-stop switch offers reliable control.

What’s inside

The kit includes a wide range of discs and accessories to support metal finishing, polishing, deburring, cleaning, and beveling tasks. Beyond the 22 discs, you get wrenches, a quick-change disc with a 1/4 inch holder, a spare 1/8 inch collet, and a standard air connector so you can begin right away on metal, plastic, stone, or wood projects.

• 2 wool grinder discs (50 mm)
• 5 zirconium corundum turn-lock discs (80 grit)
• 5 brown corundum discs (80 grit)
• 5 non-woven scouring pads (400 grit)
• 2 wrenches
• 1 quick-change disc with 1/4 inch holder
• 1 spare 1/8 inch collet
• 1 American standard air connector

Applications in real life

This tool excels in metal precision grinding, edge beveling, and surface finishing across automotive components, machinery panels, and workshop projects. The design supports access to tight corners, while the rear exhaust helps maintain a clean workspace. You can use it for cutting, polishing, smoothing, deburring, chamfering, and internal processing across a variety of materials.

Pro tip: add a few drops of lubricating oil to the air inlet before each use to keep moving parts lubricated and to encourage smooth operation over time.
