Professional Performance Guarantee: Workshop-tested for demanding applications.
The flexible head rotates 360 degrees and locks at any angle, letting you reach tight spaces that straight and angled die grinders can't access. Ideal for port and polish work inside engine heads, deburring inside tubes and housings, and finishing welds in confined spaces. At 20,000 RPM, it delivers precise material removal with carbide burrs, mounted points, and small grinding wheels.
The 1/4" collet accepts all standard 1/4" shank accessories: carbide burrs, mounted grinding points, sanding drums, flap wheels, and small cut-off wheels. Any 1/4" shank rotary accessory will fit.
A straight die grinder is simpler and more rigid — better for flat surfaces and open access. The flexible head grinder sacrifices some rigidity for vastly improved reach in tight spaces. Many shops keep both: the straight grinder for general work and the flexible for hard-to-reach areas.
The LE-G2543R requires 4 CFM at 90 PSI for full speed. An inline air regulator is recommended to fine-tune RPM for different materials — lower speed for aluminum, full speed for steel.
| Accessories | All 1/4" shank mounted points, burrs, stones, drums, and polishing bobs |
| Air Compressors | 5-6 CFM at 90 PSI |
| Materials | Steel, aluminum, wood, plastic, fiberglass, ceramic |
Ideal Applications: hard-to-reach grinding, flexible access deburring, port polishing, mold cavity finishing, pipe interior work, complex geometry finishing
The flexible shaft allows the grinding head to reach into tight spaces — engine compartments, pipe interiors, and confined areas — that rigid straight or angle grinders cannot access.
The LE-G2543R accepts any 1/4" shank grinding stones, carbide burrs, sanding drums, and polishing wheels — the same accessories used with standard die grinders.
The flexible shaft allows approximately 90° of articulation from the main body axis. This lets you grind, polish, and deburr inside enclosed spaces, around corners, and at compound angles that neither straight nor angle grinders can reach. Think of it as a combination of a die grinder and a flexible shaft tool.
At 20,000 RPM, the LE-G2543R delivers comparable cutting speed to straight die grinders. The flexible shaft does absorb a small amount of power compared to a rigid connection, but for finishing, deburring, and detail work, the performance difference is negligible. The access advantage far outweighs any minor power difference.
Insert your grinding bit, burr, or mounted point into the 1/4" collet and tighten firmly using the included wrenches. Connect to your air line via the 1/4" NPT inlet at 90 PSI. The flexible shaft allows the grinding head to articulate into angles that rigid grinders cannot reach. Run the tool at no load for 30 seconds before engaging the workpiece to ensure the collet is secure. Always run the tool at full speed before contact — loading a slow-spinning grinder can cause the bit to catch and kick.
