Machine and tool maintenance products keep machine tools and cutting tools clean, protected, and ready for the next use. Cutting tool sharpeners renew cutting edges on drill bits, end mills, knives, and blades so they can make clean, accurate cuts. Bolt and screw extractor tools remove broken fasteners from tapped holes. Machine spindle cleaning tools remove chips and other debris that can damage machine tool spindles, toolholders, and sleeves. Parts washing baskets hold workpieces, tools, and machine tool components during cleaning. Spindle conversion kits adapt a spindle of one DIN standard to accept a toolholder of another standard. Tool wrap and coatings form a protective layer that prevents damage to tools and parts.
