The Metabo HPT GP 400 (646053420) is a 1/4 in. corded paddle switch die grinder engineered for deburring, milling, grinding, and cutting in hard-to-reach areas. Featuring an extended grinding spindle and a slim, ergonomic body, this die grinder provides exceptional reach and control when working inside recessed, narrow, or awkward workpieces.

Driven by a 400 W motor operating at 30,000 RPM no-load speed, the GP 400 delivers rapid material removal for metalworking and industrial applications. The paddle switch automatically cuts power when released to enhance operator safety. A 43 mm (1-11/16 in.) precision collar enables secure clamping into stationary fixtures, while a removable rubber nose cap insulates against heat and delivers additional grip during handheld operation.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery. We use USPS, which typically takes 2-8 days for delivery, depending on your location, for smaller items and UPS Ground for all other ground shipments under 150 pounds.

• Returns: We accept returns and exchanges for a fee up to 30 days in unopened, new, and unused condition in the original packaging. Exceptions apply.

If the item qualifies for free shipping, you will be charged the original shipping cost and are responsible for shipping the product back with the shipping carrier of your choice.

We must receive the item undamaged. We recommend you package it accordingly and purchase insurance for higher-priced items to ensure you receive the full refund minus any incurred fees as applicable. We reserve the right to refuse the return of accessories.
