Dewalt Accessories DAH99414PB Pilot Bit 135 Split Point 10 Pack

Product Description

The DEWALT ACCESSORIES DAH99414PB is a 4.25-inch pilot drill bit sold in a pack of 10, designed for use with hole saw arbor systems. It features a 135-degree split point geometry that starts cutting on contact, reducing bit walking on steel surfaces and improving hole placement accuracy. The 1/4-inch diameter shank fits both quick-change and standard non-quick-change arbors, allowing the bit to transfer between arbor types without tools. This bit is suited for licensed tradespeople and experienced DIYers who need repeatable, clean pilot holes when running hole saws through steel.

This pilot bit is intended for metal drilling applications where a hole saw arbor is required, including sheet metal, electrical enclosures, HVAC ductwork penetrations, and similar steel substrates. The tool-free change mechanism integrates with DEWALT RAPID LOAD hole saw arbor systems, reducing downtime during bit changes on the job. The pack of 10 supports extended production runs or multi-tech tool kits where consumable inventory matters.
