Titanium Step Drill Bit #3T
Features
- Single-fluted design eliminates skidding and makes for easier resharpening.
- Anti-skid tip eliminates the need for center punching or pilot hole drilling.
- Similar to Klein high-speed step-drill bits, but with a titanium-nitride coating (82 - 86 Rockwell C hardness).
- Bits are perfect for drilling accurate, round holes in thin (up to 1/8'' [3 mm]) metal (steel, brass, aluminum and copper), as well as plastic and wood.
- Coating reduces friction for cooler, smoother running without lubrication; allows bits to last up to 4 to 5 times longer tha nsteel drill bits.
- Laser-etched hole sizes are easy-to-read and permanent.

Klein Tools 59003T – Frequently Asked Questions
1) Do I need to center punch or drill a pilot hole before using the Klein 59003T step bit?
No. The 59003T has an anti-skid tip that starts the hole without center punching or a pilot hole. The single-flute design also keeps it from skidding across the surface as it bites, which is why you can lay it straight on sheet metal and go.
2) How thick a piece of metal can the Klein Tools 59003T titanium step drill bit cut?
Up to 1/8 inch (3 mm) material. It is built for thin stock, steel, brass, aluminum and copper, plus plastic and wood. Anything thicker than 1/8 inch is outside what this bit is meant for, so for heavy plate you want a standard twist bit or a hole saw instead.
3) What is the difference between the Klein titanium step bits and Klein's high-speed steel step bits?
Same basic step-drill geometry, different coating. The 59003T carries a titanium-nitride coating rated 82 to 86 Rockwell C. That coating cuts friction so the bit runs cooler and smoother without lubricant, and Klein states it lasts four to five times longer than steel drill bits. If you are punching a handful of holes occasionally, the plain high-speed version does the job; if you are running panel and box knockouts all day, the titanium version is the one that survives it.
4) Do I need cutting oil with the Klein 59003T step bit?
Not required. The titanium-nitride coating reduces friction enough that the bit runs cooler and smoother without lubrication, which matters when you are drilling overhead in a panel or a device box and do not want oil running down the wall.
5) How do I know which step I am on when drilling with the Klein step bit?
Hole sizes are laser etched onto the steps, so they read clearly and will not wear off the way ink or stamped-and-painted markings do. You can check your diameter mid-cut instead of counting steps.
6) Can the Klein 59003T step bit be resharpened?
Yes. The single-flute design is what makes it practical, there is one cutting edge to dress rather than a pair to keep matched. Bear in mind that grinding the edge removes the titanium-nitride coating on the reworked surface, so a resharpened bit cuts like bare steel at that point.
7) What is the part number for the Klein #3T titanium step drill bit?
Klein Tools 59003T is the manufacturer part number, catalogued as the Titanium Step Drill Bit #3T. Order by 59003T if you are matching an existing bit in a tech's kit, the T suffix is what separates the titanium-nitride version from the plain high-speed Klein step bits.
