Klein Tools 59009T – Frequently Asked Questions
1) How thick of metal can the Klein 59009T step drill bit cut through?
The 59009T titanium step bit is built for thin metal, up to 1/8 inch (3 mm). That covers steel, brass, aluminum and copper, plus plastic and wood. Going thicker than 1/8 inch is outside what this bit is meant to do, so for heavier plate you want a different tool.
2) Do I need to center punch or drill a pilot hole before using this Klein step bit?
No. The anti-skid tip on the 59009T eliminates the need for center punching or pilot hole drilling. The single-fluted design also keeps it from skidding as it starts, so you can go straight into the sheet metal or enclosure wall.
3) What is the difference between Klein's titanium step bits and the plain high-speed steel ones?
Same basic bit, different coating. The 59009T carries a titanium-nitride coating rated 82 to 86 Rockwell C hardness. That coating cuts friction so the bit runs cooler and smoother without lubricant, and Klein states it lasts 4 to 5 times longer than steel drill bits. If you are punching a handful of holes now and then, the plain high-speed version does the job; if you are drilling enclosures and panels all day, the titanium pays back.
4) Do I have to use cutting oil with the Klein 59009T step bit?
No lubricant required. The titanium-nitride coating reduces friction so the bit runs cooler and smoother without it. That matters on a service call where you are drilling a panel overhead and do not want oil running down the wall.
5) Will this step bit make clean round holes for conduit connectors and panel knockouts?
That is what it is built for. Klein rates the 59009T for accurate, round holes in thin metal, which is the enclosure, panel and device box work an electrician does daily. Because it steps up in stages you can stop at the size you need rather than swapping bits.
6) How do I tell which step I'm on when drilling with this bit?
Hole sizes are laser-etched into the steps of the 59009T, so the markings are easy to read and permanent. They will not wear off the way ink-stamped sizes do after a few dozen holes.
7) Can the Klein 59009T be resharpened when it dulls?
Yes. The single-fluted design makes the 59009T easier to resharpen than a multi-flute bit, because there is only one cutting edge to dress. That is part of why a step bit stays in a working electrician's kit for years instead of getting thrown out.
8) What is the exact part number for the Klein #9T titanium step drill bit?
Order it as Klein Tools 59009T. That is the manufacturer part number, and the T on the end is what separates the titanium-nitride version from Klein's uncoated high-speed step bits. Worth confirming when you are standardizing a crew's kits so everyone gets the same bit.
