13PCS Bi Metal Hole Saw 13 Pieces 210mm Hole Saw 64HRC-69HRC

Our Bimetal Hole Saws are precision cutting tools designed for machinable materials up to 38mm thick. Featuring High Speed Steel teeth electron welded to a high Carbon steel body for maximum durability and long working life.

The 4/6 variable pitch tooth design improves chip clearance and reduces feed pressure with varying gullet depth. This design minimizes heat buildup, keeping teeth sharp longer for faster, more aggressive cutting performance.

For optimal performance and to extend hole saw life by 500%, we recommend using a cooling lubricant when cutting.

Available in sizes from 14mm to 210mm diameter, our Bimetal Hole Saws are compatible with portable electric tools, air tools, drill presses, lathes, boring mills, and milling machines with rotating spindles.
