Irwin 73324 – Frequently Asked Questions

1) Will the Irwin 73324 Turbo Max drill bit fit a standard 3/8 inch keyless drill chuck?
Yes. The 73324 is a 3/8 inch bit with a three-flatted shank, which Irwin puts on all sizes 3/16 inch and above. The flats give the chuck jaws something to bite, so the bit is far less likely to spin in the chuck under high torque. It drops straight into a 3/8 inch or larger keyless or keyed chuck on a portable drill or driver.
2) Do I need to center punch before drilling with the Irwin Turbo Max 73324?
No. The 135 degree split-style Turbo Max tip is self-centering, so it bites instead of walking, including on curved stock like pipe and tube. That is the main practical difference from a conventional 118 degree point, which generally does need a punch mark or a pilot divot to start true.
3) Is the Irwin 73324 bit meant for drilling steel, or can I use it in wood and plastic too?
It is built for metal. The 73324 is high-speed steel with a 135 degree precision-ground point, which is the geometry used for drilling steel and other metals. It will cut wood and plastic, but a 135 degree point is flatter than a brad point or a 118 degree wood bit, so it tends to tear rather than leave a crisp rim in those materials. For metal work on a portable drill, it is the right tool.
4) What does jobber length mean on the Irwin 73324, and will it reach through thick material?
Jobber length is the standard general-purpose flute length for a twist bit, and it is the configuration this 3/8 inch Turbo Max bit ships in. It suits ordinary plate, box, strut and tube work with a portable drill. If you need to reach deep into an assembly or through a chassis, you want an aircraft-length or extended bit instead, not a jobber. Stub or screw-machine length is the choice when you want more rigidity and less flex in tough stock.
5) What is the exact part number to reorder this 3/8 inch Irwin Turbo Max bit?
Order Irwin 73324. That number covers the 3/8 inch Turbo Max jobber length high-speed steel bit, and 3/8 inch is the only size under that part number. It is sold as a single bit, not a set, so for a facility or MRO crib stocking multiple diameters you would order the matching Turbo Max part number for each size separately.
6) Is the Irwin 73324 a solid carbide bit?
No, and that matters if you are drilling hardened or abrasive material. The 73324 is high-speed steel, not carbide and not cobalt. HSS handles mild steel, stainless in light duty, aluminum, brass and sheet metal well, and it is more forgiving of flex and side load than carbide, which chips. For work-hardened stainless or spring steel in volume, step up to a cobalt or carbide bit.
7) Will a black and gold oxide bit like the Irwin 73324 hold up in a damp truck or jobsite box?
The black and gold oxide finish on the 73324 is there for corrosion resistance, which is what you want on a bit that lives in a service van or a gang box rather than a climate-controlled shop. The oxide also helps the bit shed chips and resist galling in steel. It is a surface treatment, not a titanium or carbide coating, so it does not change the bit's base hardness, which comes from the high-speed steel body.
8) Can I use the Irwin 73324 in a drill press as well as a cordless drill?
Yes. It is a straight-shank jobber bit, so it chucks into a drill press, a mag drill with a chuck adapter, or a hand-held cordless drill. Irwin designed the Turbo Max tip specifically with portable drill users in mind, since the self-centering point compensates for the wobble you get drilling freehand. In a press you simply get the same hole with less effort.
