Long Shaft Pneumatic Air Die Grinder | OEM/ODM Wholesale | LEMATEC Tools Taiwan-Made
Unmatched power meets impossible reach—the 1.0 HP LE-AG290 series is the definitive professional solution for deep-space industrial grinding.
LE-AG290 1.0 HP Extended Air Die Grinder Series for Deep-Reach Grinding and Weld Treatment
Four shaft-length options from 5.5 to 31 inches help tool brands, distributors, automotive repair teams, and industrial users match reach to the work area while keeping the shared 1.0 HP platform, 21,000 RPM free speed, 1/4-inch (6mm) collet, and 4.2 CFM air-consumption specification.
Choose the LE-AG290 series when the job needs a pneumatic die grinder with extended reach for deep chassis areas, weld seams, internal edges, or other access-limited work. Select the shaft length by access depth, confirm the 1/4-inch (6mm) accessory interface, and verify compressor delivery against the listed 4.2 CFM air-consumption specification. For OEM/ODM, private-label, samples, packaging, MOQ, documentation, and lead-time details, contact LEMATEC for confirmation.

Official Product Images and Engineering Features
Extended Shaft Options for Difficult Access
The series is presented in four shaft extensions: 5.5 inches, 12 inches, 21 inches, and 31 inches. This supports reach-based selection for deep chassis areas, weld seams, abrasive polishing, and other access-limited work.
360° Rear Exhaust
The supplied source describes a 360° rear exhaust layout that directs exhaust away from the operator area. Confirm the actual work environment, ventilation, and PPE requirements before use.
Self-Locking Trigger and Regulator
The source lists a self-locking trigger and integrated regulator for HI/LO speed control, with free speed listed up to 21,000 RPM. Match speed and accessory choice to the workpiece.
1/4-inch (6mm) Industrial Collet
The supplied specification identifies a 1/4-inch (6mm) collet and includes stop spanners for accessory changes. Confirm accessory compatibility before ordering.
Choose the Right Tool for the Work Area
Use this table to separate the job requirement from the tool category. It is a selection guide, not a claim that one tool replaces every other grinding or sanding method.
| Work requirement | Tool direction to consider | Buyer confirmation |
|---|---|---|
| Grinding or deburring in a deep, narrow area | Extended air die grinder such as the LE-AG290 series | Required shaft extension, total length, accessory reach, and operator control. |
| Localized detail grinding or polishing | Standard or shorter-shaft air die grinder | Collet, accessory, speed control, air supply, and hand clearance. |
| Broader surface finishing | Air sander or another surface-finishing tool | Pad or abrasive type, contact area, finish target, and working time. |
| Large-area or different-angle material removal | Angle grinder category may be more appropriate | Disc/accessory type, guard requirements, access, and safety procedure. |
Selection boundary: The LE-AG290 is a pneumatic extended die grinder series. It should not be represented as a universal substitute for an air sander or angle grinder without confirming the workpiece, accessory, reach, and finish requirement.

Use appropriate PPE, guarding and ventilation, and confirm accessory rating, collet fit, workpiece stability, and operator clearance.
Frequently Asked Questions
What is the LE-AG290 series best suited for?
It is suited to pneumatic grinding, weld treatment, polishing, and deburring where extended shaft reach helps access deep or restricted work areas.
How do I choose between the 5.5-inch, 12-inch, 21-inch, and 31-inch versions?
Start with the required access depth and select the shortest shaft that reaches the work area while preserving control. Confirm total length and weight for the intended operator and task.
Is the LE-AG290 an air sander or angle grinder replacement?
No universal replacement should be assumed. A die grinder, air sander, and angle grinder serve different access, accessory, contact-area, and finish requirements. Use the comparison table and confirm the application with LEMATEC.
What information should be included in an OEM or wholesale inquiry?
Include target model or shaft length, estimated quantity, target market, accessory requirements, packaging or private-label needs, sample request, available air conditions, and desired documentation. MOQ, lead time, and commercial terms are confirmed case by case.
