Ingersoll Rand 302B Angle Die Grinder – 20,000 rpm, 0.33 hp, 1/4 in Collet, Rear Exhaust

Overview

Meet the Ingersoll Rand 302B Angle Air Die Grinder, a compact, reliable tool built to tackle a wide range of grinding and polishing tasks in shop or field settings. Powered by a robust motor that delivers 0.33 hp and a free speed of 20,000 rpm, it balances power with precision to handle detailing as well as material removal where it matters most.

Weighing about 1 lb, this grinder stays nimble in the hand. The lightweight, durable composite housing resists cold air and helps reduce fatigue during longer sessions, while the integral safety-lock throttle helps prevent accidental starts for added peace of mind.

Durability and balance

The 302B uses ball-bearing construction to improve balance and minimize vibration, supporting longer tool life in demanding environments. A built-in lubricating wick helps maintain the angle gearing, contributing to consistent performance and less frequent maintenance in tough settings.

Ergonomics, safety, and airflow

Designed for comfortable handling, the tool’s ergonomic housing reduces hand strain during extended grinding or polishing tasks. The rear exhaust directs air away from the operator, improving comfort and workspace visibility. For added safety, the throttle lever locks when not in use, preventing unintentional starts.

Versatility and included tooling

This model ships with two wrenches and includes a 1/4 inch collet and a 6 mm collet, enabling quick switching between accessories for different tasks. A broad accessory set makes it suitable for metalworking, automotive work, and hobby projects alike.
