Hand or pneumatic tool that forces grease into bearings and fittings to reduce wear and ensure smooth operation.
Grinder
Rotary power tool used with different wheels for grinding, cutting, sanding or polishing materials like metal, masonry, and tile.
Glass cutter
Handheld tool with a hardened wheel or cutter that scores glass to create clean breaks for windows and crafts.
Gimlet
Simple hand tool with a threaded screw tip for boring small holes and starting screws in wood without a drill.
Gouge
Chisel-like carving tool with a curved cutting edge used to scooped or shape wood and create hollows or profiles.
G-clamp
Clamp shaped like a “G” that provides strong, adjustable clamping pressure for gluing, welding, or machining setups.
Gear puller
Tool with arms and a center screw to pull tight-fit parts off shafts without damaging components.
