3/8'' Hex Arbor with Pilot Drill

The L.H. DOTTIE V34 accessory combines a 3/8'' hex arbor with an integrated pilot drill. It features a 1/2''-20 thread size for mounting compatible hole saws or cutters. The tool is supplied new and intended for use with power or pneumatic drills.

Suited for installers cutting precise holes

This arbor suits tradespeople who need a secure hex-shank connection and a built-in pilot bit for accurate starts. Buyers requiring a different thread pitch or a larger shank diameter should look at other options. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Simple chuck installation with pilot alignment

Installation consists of tightening the hex shank into a drill chuck and threading the cutter onto the 1/2''-20 spindle. The pilot drill centres the cut automatically. The most common issue is thread damage if the cutter is forced on cross-threaded.

Questions about this item

What size hex shank must my drill or impact driver accept to use this arbor?

The arbor has a 3/8 inch hex shank, so the chuck or adapter on your tool must accommodate that size.

Will the 1/2-20 thread on this arbor match the hole saws I already own?

It fits hole saws and cutters with a 1/2-20 internal thread; check the marking on your existing saws to confirm compatibility.

How can I verify the pilot drill is seated correctly before cutting?

The pilot drill should protrude evenly beyond the saw teeth and spin freely without wobble when the tool is running unloaded.
