4" 5" Air Angle Grinder 13500RPM LE-AG849A
Function
LE-AG849A Mg-Al Air Angle Grinder
The Lightweight Champion of Heavy Fabrication.
Engineering the future of naval architecture and heavy construction with the ultimate balance of Magnesium-Aluminum alloy durability and high-torque precision.
The Primary Asset for Naval Architecture & Shipyards
In shipbuilding and heavy fabrication, tools aren't just used; they are pushed to the absolute limit. The LEMATEC LE-AG849A utilizes a Magnesium-Aluminum housing to solve the industry’s greatest challenge: providing heavy-duty grinding power without the debilitating operator fatigue of standard steel tools. This is a strategic acquisition for procurement officers seeking both performance and OHS compliance.

Industrial Features & Engineering Logic
Mg-Al Lightweight Housing
The core of the LE-AG849A is its advanced Magnesium-Aluminum alloy body. This material is **1.5x more durable** than standard cast aluminum and significantly lighter than steel, offering superior impact resistance and natural heat dissipation for continuous high-load operation.
Precision Bevel Gear Drive
Equipped with specially treated precision-machined bevel gears, the LE-AG849A delivers smooth, vibration-isolated power. This reduces the risk of vibration-induced injury (HAVS) and ensures that 100% of the pneumatic power is translated into aggressive material removal.
HEAVY CORE
Heat-Treated Cylinder with Precision Surface Grinding for maximum rotational stability and zero performance drop-off.
