The shipper and the synchronous wheel are equipped with the 1mm insulation gasket to tightly. The rotation is smooth without phase grinding, and the accuracy is good;No power spindle, precision machining by grinding machine, precision of 0.005mm, that is, a high precision spindle with less than one thread. DIY bench drill, bench grinder, table saw and so on. Through the connecting rod, the shaft sleeve link is eliminated, and the drill clamp is installed directly, so the accuracy is higher. The non-driven spindle (Mohs chuck connecting rod) is precision machined with a grinding machine with an accuracy of 0.005MM. Can be used to drill bench drills, bench mills, table saws, etc. Specification: Cutting ability: Unpowered spindle Cutting depth: 10 (mm) Saw blade size / diameter: 90 x 10 (mm) No-load speed: 10000 (RPM) Scope of application: Making small saw Power type: No power colour: silver Material: Metal Package Contents: 1 X Drill chuck connecting rod 1 X XL20T 10mm hole synchronization wheel 1 X 10mm hole slider (including 2 bearings) 1 X 1.5-13mm B16 Drill Chuck 1 X M10 Shaft sleeve 1 X XL10T 5mm hole synchronization wheel 1 X 120XL Timing belt 1 X Wrench Installation tips: 1. Pay attention to the mounting direction of the bearing, and carefully look at the description diagram or video. 2. Do not damage the bearing blindly. Patience and diligence are the main points of mechanical work. 3. Various methods: activate the brain and complete the assembly. 4. The sliding block and the contact of the synchronous wheel are separated by gasket to prevent phase grinding. the gasket is small. Do not lose. Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
