AUTOMOTIVE TAPER REAMER END MILLS

FEATURES & BENEFITS
We designed our Conical Automotive Tapers with a left hand spiral and right hand cut, to get the most out of the high speed steel and create a superior surface finish. The addition of a cylindrical land design creates a smooth cutting tool that can handle the needs of the automotive industry. We pride ourselves on being an expert resource, to all our partners and industries, with results that can be reproduced without exception.

RESULTS
Designed for reaming ball joints and tie rod ends, the left hand spiral and right hand cut end mills, offer a slow spiral to avoid grabbing the material, while milling the intended area. At 1-1/2 Taper Per Foot, these tapered end mills are used on “through holes” or “predrilled holes” for heavy construction vehicles, recreational vehicles (ATVs), buses, snowmobiles and golf carts. The simple fact is our end mills are astonishingly effective and leave no need for us to make claims when the results are irrefutable.

PRODUCTION ENHANCEMENTS

Proper tool setup and selection can improve your running parts by nearly 3 fold. Rather than using a 7 multi-axis machine and substantial programming time to cut a draft angle, the use of our tapered end mills were able to improve the finish and dramatically increase production results.
