Question 1

What hole sizes are included in this SHOCKWAVE Electrical Step Bit set?

Accepted Answer

This 3-piece electrical step bit set covers a wide range of hole diameters. The #1 bit handles 1/8 to 1/2 inch, the #4 bit covers 3/16 to 7/8 inch, and the #9 bit creates 7/8-inch and 1-1/8-inch holes. Laser-engraved markings help identify each step and stop at the desired size.

Question 2

Can these electrical step bits be used with impact drivers?

Accepted Answer

Yes. These SHOCKWAVE Impact Duty step bits are optimized for impact drivers and are also compatible with drill/drivers. Each bit uses a 1/4-inch hex shank with an optimized SHOCKZONE body designed to reduce early shank breaks. This makes the set suitable for electrical drilling applications where users need a durable bit for impact-rated cordless tools.

Question 3

How does the TiAlN coating affect the life of these step bits?

Accepted Answer

The Titanium Aluminum Nitride, or TiAlN, coating is designed to improve durability and resistance to wear during repeated drilling. According to the product information, it provides up to 5X longer life than competitive impact step bits. This can make the set useful for professionals who regularly create multiple hole sizes and need longer-lasting drilling accessories.

Question 4

How do the Rapid Strike tip and dual spiral flute improve drilling speed?

Accepted Answer

The Rapid Strike tip is designed to provide fast, accurate starts, while the dual spiral flute helps remove material efficiently as the hole develops. Together, these features are stated to deliver up to 2X faster hole drilling. This combination can help improve productivity when drilling multiple holes with an impact driver or compatible drill/driver.

Question 5

What does the SHOCKZONE body do during impact drilling?

Accepted Answer

The optimized SHOCKZONE body is designed to improve the durability of the step bit when exposed to the repeated forces of an impact driver. Its construction helps reduce early shank breaks, while the 1/4-inch hex shank provides compatibility with impact drivers and drill/drivers. This design supports more reliable performance during demanding electrical drilling applications.
