Hold end mills, drills, and reamers securely in manual milling machines that have an R8 taper spindle.

Convert tools with a Morse taper shank to an R8 shank for use in manual milling machines that have an R8 taper spindle.

Hold and center high-speed steel slitting saws.

Each of these sets comes with three differently sized arbors.

Mount these arbors into manual milling machines that have an R8 taper spindle.

The integral arbor is more rigid for greater accuracy than a drill chuck used with a separate arbor.

A ball-bearing design provides increased gripping force to keep bits from slipping, which allows these chucks to take on high-torque drilling applications. Also known as super chucks.

For better control when drilling small holes with a drill press or milling machine, the attachment on these arbors lets you apply light feed pressure with your fingers while the machine rotates the bit.
