Irwin 3016006 – Frequently Asked Questions

1) What sizes do the Irwin cobalt split point jobber bits come in?
Four diameters are offered: 3/32 inch (MPN 3016006), 1/8 inch (3016008), 7/32 inch (3016014), and 7/16 inch (3016028). Each is sold as a single bit, not a set, so you can restock just the size you burn through.
2) Will a cobalt drill bit cut hardened steel and stainless alloys, or do I need carbide?
The Irwin cobalt jobber bit is built from cobalt alloy steel specifically for abrasive alloy metals and hardened steel, because cobalt holds its edge when the hole gets hot. That covers most MRO and fab work in steel, stainless and tough alloys. Carbide is the step you take for masonry or extremely hard tool steel, not for the general metal drilling this bit is made for.
3) What does the 135 degree split point actually do for me on sheet metal and round stock?
A 135 degree split point is a flatter, self-centering tip, so the bit bites where you put it instead of skating across the surface. On thin sheet metal, electrical enclosure panels or round bar where a center punch is awkward, that is the difference between an on-location hole and a scarred panel. The flatter angle also reduces thrust needed compared with a standard 118 degree general purpose point.
4) Are these Irwin bits sold as a single bit or in an index set?
Each order is one bit in individual packaging. If you are standardizing a maintenance cart or a van stock, order the sizes you repeat most, for example 1/8 inch and 7/32 inch, rather than buying a full index and losing the odd sizes.
5) Which bit size do I use to tap a 1/4-20 thread?
The tap drill for 1/4-20 is 13/64 inch; the closest size in this Irwin cobalt range is 7/32 inch (MPN 3016014), which is slightly oversize and gives a lower thread engagement. For a full-depth 1/4-20 thread, use a 13/64 inch bit instead. The 7/32 inch is the right pick when you want a clearance-ish fit or are drilling for a self-tapping screw in thinner stock.
6) Is a jobber length bit long enough to drill through a steel stud or channel?
Jobber length is the standard, general purpose shank-and-flute length and gives more usable flute than a stubby or screw-machine bit, which is what you want for through holes in studs, strut and plate. For deep holes beyond jobber reach you move to an aircraft-length or extension bit instead.
7) Can I run these bits in a cordless drill or do they need a drill press?
These are standard round-shank jobber bits with no power source of their own, so they chuck into a cordless or corded drill, a mag drill chuck, or a drill press. In a handheld drill the split point matters most, since it starts the hole without a punch. In steel, slower speed with cutting oil is what gets full life out of a cobalt bit.
8) Where are Irwin 3016 series cobalt bits made?
Country of origin is China. That matters on public and institutional work where a Buy American or domestic-preference clause applies, so check your spec before submitting these on a federally funded job.
