Product Overview

Inspired by the iconic MK II Grenade, the handle features a rugged tactical design with a solid grip that prevents slipping, scratching, or discomfort during use.

This kit comes with the One-Touch Quick-Change System, allowing fast valve head replacement, while also supporting 6.35mm standard bits for versatile applications.

The handle is crafted from forged 6061-T6 aluminium with an anodized surface finish, ensuring both durability and strength.
The valve components are made of 1144 medium carbon steel, heat-treated to around 47 HRC. The surface is treated with a non-electroplated, heavy-metal-free, solvent-free physical coating process, providing multiple metallic textures while being more durable, eco-friendly, and safe.

Packaged in a storage case for easy organisation. The case also features a thoughtful Lock design, keeping tools secure during transport and storage.
