Freud DHS4BITII Hss Pilot Bit 1/4 Inch Hex Shank

Product Description

The FREUD DHS4BITII is a 1/4-inch High Speed Steel (HSS) hex shank pilot bit designed as a direct replacement for use with Freud Diablo hole saw arbors. Pilot bits center the hole saw before cutting begins, preventing walk and improving cut accuracy in wood, plastic, and light metals. This bit features a hex shank for secure tool-free bit changes on compatible arbors. It is a consumable component that wears with use and is sold in a package of 5, giving tradespeople and installers a ready supply for ongoing work.

This pilot bit is suited for residential and light commercial installation work where Freud Diablo hole saw arbors are in regular use. Typical applications include electrical rough-in, plumbing penetrations, and HVAC duct and cabinet work where repeated hole saw use demands periodic pilot bit replacement. Having spares on hand reduces downtime during production drilling tasks.

Installation Notes

Installation is performed by tradespeople using compatible Freud Diablo hole saw arbors. Ensure the arbor is removed from the drill or driver before swapping the pilot bit. Seat the hex shank fully into the arbor collet and confirm it is locked before resuming drilling. Replace the pilot bit when tip wear causes centering loss or reduces penetration performance.
