Milwaukee 48-89-9224 – Frequently Asked Questions

1) Will these step bits hold in a keyless cordless drill chuck without spinning out?
The shanks are Milwaukee's 3-Flat Secure-Grip design, which gives the chuck jaws flats to bite on and cuts down bit slippage. The set is also optimized for cordless drills run in high speed, with claimed cutting up to 2X faster and up to 50 percent more holes per battery charge.
2) How do I know when to stop drilling to get the exact hole size with a step bit?
Each step carries laser-engraved reference marks, so you can read the size off the bit and stop on the hole you want instead of counting steps. That is the practical difference on panel and enclosure work where a connector or knockout has to fit the first time.
3) Can I use the Milwaukee 48-89-9224 step bit set to drill through concrete or masonry?
No. The Milwaukee 48-89-9224 is a 6-piece step drill bit set with black oxide coated, dual-flute geometry intended for drilling and enlarging holes in sheet material such as electrical enclosures, panels, and thin metal. For concrete or block anchors you need a hammer-rated masonry bit instead, such as the Minerallac 59736 Relton 1/2 inch x 6 inch carbide-tipped rotary/percussion drill bit, which is built for percussion drilling. Running a step bit in a rotary hammer will destroy the step bit and will not cut the hole.
4) What is the Milwaukee part number for the 6-piece step drill bit set?
Order it as Milwaukee Tool 48-89-9224. That MPN covers the complete 6-piece step drill bit set, and it is the number to quote if you are matching an existing set already in the van.
5) Step drill bit or a hole saw for drilling sheet metal enclosures and panels?
For thin sheet metal, electrical enclosures, and panel boxes, a step bit is the better tool: it self-starts, deburrs as it steps up, and gives you multiple hole sizes from one bit without a pilot arbor. Hole saws take over once you need large diameters or thicker stock. Milwaukee's 48-89-9224 set is a six-bit step set with a Rapid Strike tip for fast, accurate starts and a dual-flute JAM-FREE design for speed and control in thin material.
6) I need one clean 5/8 inch hole in tile or stone, not a range of sizes in metal. What should I order instead of the Milwaukee 48-89-9224 step bit set?
Step bits like the Milwaukee 48-89-9224 cut multiple hole diameters in thin material using laser-engraved reference marks to stop on the size you want, and they are not made for abrasive materials. For a single fixed 5/8 inch hole in a hard abrasive material, the Lenox 12111-10DGHS D/S-10Dg diamond grit drill bit in 5/8 inch is the right tool, since diamond grit abrades through rather than cutting flutes into metal.
7) For an electrician running conduit, what is the difference between carrying the Milwaukee 48-89-9224 step bit set and a carbide percussion bit?
They cover two different parts of the same rough-in. The Milwaukee 48-89-9224 six-piece step bit set handles the knockout-style holes in panels, boxes, and struts, with a Rapid Strike tip for fast starts and 3-flat secure-grip shanks that resist slipping in the drill chuck. The Minerallac 59736 Relton bit is a carbide-tipped rotary/percussion bit at 1/2 inch by 6 inch, which is what you reach for when the same run needs anchor holes drilled into concrete walls or slab. Most conduit jobs need both on the cart.
8) What coating is on the Milwaukee 48-89-9224 step bits and does it affect heat buildup?
Black oxide, paired with an optimized cutting geometry. Milwaukee's claim is up to 4X longer bit life because the combination cuts faster and produces less heat, and the Rapid Strike tip also generates less heat on start. Less heat is what keeps the cutting edges from dulling early on repeated holes in steel.
9) Is the Milwaukee 48-89-9224 step bit set made in the USA?
Yes, the 6-piece step drill bit set is listed as made in the USA. That matters on government and institutional purchase orders carrying domestic sourcing language.
