Includes (2) Allen wrenches, chuck key, and, believe it or not, an instruction booklet that is easy to understand.

That’s what we say about this drill pump! Screw hoses to the threaded inlet and outlet valves (3/4”-14 standard garden hose size) and attach the 1/4” dia. shaft to your drill.

You get a 4-pack of standard 1/4" hex-shaped driver bits that are 6" long for those hard-to-reach screw-heads. Includes a 1/4" slotted driver plus #1 & #2 Phillips and a #2 Robertson in case you're Canadian.

Nobody will ever call you Dusty again if you're wielding this Roan Model S7250 dust-collecting circular saw.

Includes a Lydall HMWP filter designed to last the life of the saw in a chamber large enough to go 50-60 cuts before emptying. Corded to run on AC power. The saw’s new, in the box -- but it’s priced at half the original retail price, Dusty.
