Diablo Hole Saw Pilot Bit DHS2BITCB 1/4 x 2 Inch Carbide Tipped (Snap Lock Plus Mandrel Steel Demon Metal Stainless Sheet Penetration)

Diablo DHS2BITCB Steel Demon 1/4-Inch x 2-Inch Carbide-Tipped Hole Saw Pilot Bit

The Diablo DHS2BITCB is a 1/4-inch diameter by 2-inch overall length carbide-tipped hole saw pilot bit engineered with an integrated depth-stop collar and ejection spring for center-guided metal drilling up to 1/4 inch (0.25 in) thick. Built with TiCo Hi-Density carbide teeth delivering 50 times extended cutting life compared to standard bi-metal bits, this high-durability pilot bit integrates directly into Diablo Snap-Lock Plus mandrel systems. Designed for electricians, HVAC technicians, and sheet metal fabricators using handheld drills or drill presses, its spring-loaded design accelerates core plug ejection while preventing bit over-drilling through electrical enclosures, stainless steel panels, and metal stud walls.

Best Used For:

• Electrical Panel Enclosure Knockout Hole Guidance: Drilling precise 1/4-inch pilot guide holes through stainless steel junction boxes and breaker panels without over-penetrating internal wiring.
• Metal Stud Framing & Sheet Metal Ductwork: Boring clean, burr-free center holes through heavy-gauge steel studs, aluminum sheeting, and corrugated metal panels.
• Stainless Steel Pipe & Tubing Penetrations: Centering hole saw cups accurately on curved stainless steel pipes and structural tubing without bit walking or edge burring.

Key Performance & Safety Features

• 50X Extended Life TiCo Carbide: Formulated micro-grain titanium cobalt carbide teeth resist friction heat and tooth dulling in tough stainless steel.
• Integrated Depth-Stop Guard Collar: Built-in mechanical stop limits drilling depth to prevent over-penetration and shield internal wiring or background materials.
• Spring-Loaded Fast Plug Ejection: Internal coiled spring pushes metal core slugs out of the hole saw cup automatically after completing cuts.
• Snap-Lock Plus Mandrel Integration: Connects quickly to Diablo universal quick-change mandrels for tool-free cup swaps and zero jobsite downtime.
• 0.25-Inch Maximum Thickness Capacity: Engineered specifically to penetrate sheet metals, steel studs, and metal plates up to 1/4 inch thick.
• 1/4-Inch Anti-Slip Hex Shank Base: Universal 1/4-inch hex shank locks firmly into drill chucks and impact drivers to prevent shank rotation under load.

What's Included

• (1) Diablo 1/4" x 2" Steel Demon™ Carbide Tipped Hole Saw Pilot Bit (DHS2BITCB)

Technical Specifications

Pro-Tip: Compress the ejection spring fully against the metal surface when initiating a cut to allow the pilot tip to establish a deep centering hole before hole saw teeth engage.
