Irwin 3220 SDS-Plus Carbide-Tip Hammer Drill Bit, Chrome Vanadium Shaft

Irwin 3220 SDS-Plus Carbide-Tip Hammer Drill Bit, Chrome Vanadium Shaft

The Irwin 3220 series SDS-Plus Hammer Drill Bits deliver fast, controlled drilling on the jobsite with a carbide tip engineered for controlled starts without walking. Built for all SDS-Plus and Hilti TE-C style rotary hammers, this bit family is available in diameters from 3/16" up to 1" and lengths from 4" up to 10", covering sizes such as 3/16" x 4", 1/2" x 10", 3/4" x 6", and 1" x 8". Every bit in the lineup features a patented flute design that clears debris quickly to reduce clogging and vibration, a short drilling head that minimizes breakout on through-holes, and a chrome vanadium shaft through-hardened to 50-53HrC for durability under repeated impact.

Key Features

• Size Range: Available in diameters from 3/16" to 1" and lengths from 4" to 10", including 3/16" x 4", 1/4" x 4", 1/4" x 10", 3/8" x 4", 3/8" x 10", 1/2" x 4", 1/2" x 10", 5/16" x 4", 5/8" x 4", 3/4" x 6", 3/4" x 10", and 1" x 8" for precise, repeatable hole sizing.
• Carbide Tip: Made to ANSI specifications for controlled starts without walking.
• Chuck Type: SDS-Plus shank fits all SDS-Plus and Hilti TE-C rotary hammers for broad tool compatibility.
• Durable Construction: Hot isostatically pressed to extend life and resist breakage.
• Patented Flute Design: Removes dust up to 25% faster than other bits, reducing clogging and vibration.
• Anti-Bind Design: Reduced area above the flute prevents binding while drilling, allowing use of the full usable length.
• Chrome Vanadium Shaft: Through-hardened to 50-53HrC for strength and wear resistance.
• Finish: Copper braze material provides high heat resistance for reduced tip loss; shot-peened, double-tempered finish reduces breakage.
