Fast, Controlled Hole Sizing for Trade Professionals

When speed & accuracy matter, ITM spiral step drills deliver flawless hole cutting through metal, plastic & sheet materials. Their spiral flutes clear chips quickly, reducing heat & preventing burrs for clean, round holes every time. Trusted by electricians, fabricators & installers, these drills give professionals smooth performance & long service life.

Each bit is crafted from premium high-speed steel or titanium-coated alloy, engineered for low friction & consistent cutting under load. Their multi-step design eliminates the need to swap drill bits, saving time during repetitive hole sizing. For precision alignment & steady feed, trades often pair them with Power Tools to maintain constant RPM during cutting.

When not in use, spiral step drills are best protected in Tool Boxes & Bags designed to prevent edge damage. Workshops storing multiple sizes keep them sorted in Tool Organizers & Inserts for fast identification. For teams on the move, Rolling Site Boxes & Chests ensure safe transport across job sites without losing calibration or finish quality.
