The new WINTER FlutePolish product range features reduced flute polishing time and improved surface quality for shank tools such as drills, end mills and reamers. The new elastic resin bond system improves flexibility allowing wheels to conform to the surface of the part being polished. A reduction of the flute polishing time by 30% can be achieved.

Shank tools such as drills, end mills, reamers and stepped tools vary
in design and geometry. The geometry is created using a specific
sequence of applications, including flute grinding, gashing, and
grinding clearance angles.
After grinding (roughing) the flute to achieve the correct geometry,
the flute can be polished to produce a better surface finish.
The polished surface improves the performance of drills and end
mills when used on aluminium alloys, hardened steel materials or
when drilling very hard wood. Polishing helps to transport material
chips efficiently out of the drilled hole to reduce friction, this also helps
to reduce the risk of chips becoming welded to the cutting edge.
Using WINTER FlutePolish is an ideal way to complete the production
of shank tools, with it improving the cutting edge of the tool and
providing a more consistent and extended tool life.
WINTER offers a complete portfolio of products for the production of shank tools through its Q-Flute range providing
super abrasive grinding wheels that are designed to make flute grinding more economical.
