Specification BatteriesRequired : 1 Brand : DIDUEMEN BulletPoint1 : NOTE: Wear goggles to prevent debris from flying when using this tool. BulletPoint2 : Strong Function: The tungsten grinder is equipped with a built-in rechargeable lithium-ion battery, but the grinding capacity is as powerful as that of a corded rotary tool. It only takes 2.5-3 hours to fully charge. When fully charged, it can grind continuously and efficiently for up to 20 minutes without interruption. BulletPoint3 : Professional Tungsten Grinding Tool:In order to grind the perfect tungsten sharp corners more professionally, accurately and quickly, 4 brass tungsten guide rails (0.04", 1/16", 3/32", 1/8" ( 1mm, 1.6mm, 2.4mm, 3.2mm)) and 4 angled (22.5°, 20°, 15°, 10°) screw holes. Guide rails and corner holes better define and stabilize the angle required for grinding, increasing efficiency and reducing wear. BulletPoint4 : One-button Speed Change: This tool is equipped with 5 speed settings from 5,000rpm to 30,000rpm, suitable for various work requirements. 4 LED lights are battery indicator. When all four LED lights are on, it is fully charged; when only one LED light is on, it needs to be charged immediately. BulletPoint5 : Easy to Use:This is a handheld tungsten steel sharpener with a small body and wireless mode that allows workers to operate without being trapped on the TIG table. Without installation and debugging, even beginners can operate tools well for tungsten grinding.Also, if the sharpener attachment is removed, the grinder can be used as a normal rotary tool. BulletPoint6 : Abundant accessories: 9*double sided grind wheels, 1* grinding guide attachment, 4* copper screw holes, 3* CNC Mandrels, 1*collar cap, 1*electric grinder, 1*charger,1*wrench, 1* storage box, 1* User Manual. Easy to store and carry.
