Full Product Description

Product Introduction

A factory-priced, portable 4-inch angle grinder built for global B2B buyers.

This Angle Grinder is the cordless 4-inch (100mm) workhorse in our 21V brushless family — a true portable angle grinder designed for one-hand operation, overhead cutting and tight pipe-run work where a full-size 125mm machine is simply too bulky. The high-output brushless motor spins the 100mm disc at up to 10 000 RPM, and the 21V lithium-ion platform delivers up to 50% longer runtime per charge than a comparable brushed model, which means lower service costs and higher end-user satisfaction for the angle grinder buyer in Southeast Asia, the Middle East, Central Asia, South America and North America.

Compact at just 1.1–1.3 kg, this cordless angle grinder fits into one hand and supports cutting, grinding, sanding and polishing via a quick-change M10 spindle. A two-position side handle, tool-free adjustable guard, spindle-lock button and dust-sealed slide switch make this brushless angle grinder safe and versatile for daily commercial work. The reinforced nylon housing in matte black with red trim, an anti-slip TPR soft grip and a 4-LED battery fuel gauge are built for the way fabricators, plumbers, electricians and serious DIY buyers actually use an angle grinder every day. Custom logos, retail color boxes and private-mold services are available for brand owners looking to launch their own 100mm angle grinder line.

Key Features & Characteristics

Six engineering highlights that make this 100mm angle grinder stand out in the wholesale market.

⚡

21V Brushless Motor · 10 000 RPM

A high-output brushless motor spins the 100 mm disc at 10 000 RPM with up to 50% longer runtime than brushed models — the cutting heart of this cordless angle grinder.

 
🪶

Lightweight 1.1–1.3 kg · One-Hand Control

A slim body with a 2-position side handle lets operators work overhead and in tight pipe runs where a full-size 125mm grinder cannot reach.

 
🪚

Cut · Grind · Sand · Polish · One Tool

A quick-change M10 spindle accepts cutting discs, grinding wheels, flap discs and wire brushes — one angle grinder covers metal, wood, stone and more.

 
⚙️

Premium Gear Head · Spindle-Lock Button

Precision-cut hardened steel gears and an aluminum gear housing deliver stable torque transfer, while the spindle lock makes disc changes a two-second job.

 
🛡️

Soft Start + Kickback Protection

Smooth ramp-up protects the motor and gearbox; electronic kickback protection cuts power instantly if the disc jams — safer for the operator on every cut.

 
✋

Ergonomic Black + Red Body · 4-LED Gauge

Matte black housing with red trim, anti-slip TPR soft grip, dust-sealed switch and a 4-LED battery fuel gauge — comfortable for long shifts and easy to monitor.
