Frequently Asked Questions

What is the IRWIN Step Drill Bit 15101ZR used for?

The IRWIN Step Drill Bit 15101ZR is used for drilling stepped holes in thin materials like sheet metal, plastic, and wood. Its TiN-coated HSS construction provides wear resistance, and the hex shank prevents slipping in drill chucks. It is not impact rated, so use only in standard drills.

What are the specifications of the IRWIN Step Drill Bit 15101ZR?

The IRWIN Step Drill Bit 15101ZR has a range of 1/8" to 1/2" in 1/64" increments. It is made of TiN-coated high-speed steel (HSS) with a hex shank for secure grip. The manufacturer part number is 15101ZR. It is not impact rated, so avoid use with impact drivers.

Where to buy the IRWIN Step Drill Bit 15101ZR worldwide?

You can source the IRWIN Step Drill Bit 15101ZR through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.

How to select the right IRWIN step drill bit size?

Select the IRWIN step drill bit based on the hole diameter range needed. The 15101ZR covers 1/8" to 1/2" in small steps, ideal for thin materials. For thicker stock, choose a larger step bit. Always match the shank type (hex) to your drill chuck. IRWIN offers multiple sizes for different applications.
