- High-speed steel construction handles repeated drilling in metal and wood
- Step design creates clean, accurate holes without multiple bit swaps
- Ideal for kitchen and bath fixture installations where speed matters
3-piece step drill set
The Big Horn 19249 set contains three titanium nitride coated high-speed steel step drill bits. Together they replace 28 individual twist bits, letting you drill multiple hole diameters without changing tools. Designed for kitchen and bath fixture installations, the set suits plumbers, electricians and DIYers who want faster bit changes on the job.
Coated high-speed steel
Titanium nitride coating reduces friction and heat build-up during drilling, which helps the cutting edges stay sharp longer. High-speed steel construction resists wear in mild steel, aluminium, plastic and wood. Normal hand-drill use produces manageable noise and vibration without excessive power draw from the drill motor.
Replaces 28 individual bits
Each step bit covers a range of diameters so one tool does the work of many separate twist drills. Buyers who need a single fixed-size hole or a larger diameter range than the three bits provide will not be served by this set.

Questions about this item
How do I install the Big Horn 19249 step drill bit, and what step do people often get wrong?
Insert the 1/4-inch hex shank fully into the drill chuck and tighten securely; the common mistake is leaving the shank partially seated, which causes wobble and uneven holes.
What maintenance or replacement will the Big Horn 19249 set need later?
The titanium nitride coating reduces friction and heat; resharpening is difficult, so replace individual bits when cutting edges dull or the coating wears through.
What limit shows up first under sustained use with the Big Horn 19249 bits?
Heat buildup in the high-speed steel softens the cutting edges fastest, especially when drilling thicker metal without cutting fluid or pauses.
