Irwin 316015 – Frequently Asked Questions

1) Will the Irwin 316015 drill bit set cut stainless and other hard metals, or is it just for wood?
The bits are cobalt alloy steel, which is what you want for drilling tougher metals as well as wood and plastic. Irwin lists the 15-piece 316015 as a general-purpose assortment covering metal, wood and plastic, so it handles mixed-material work rather than being a wood-only set. For fabrication and metalworking shops this is the material class that holds an edge longer under heat than a plain HSS bit.
2) What is the correct Irwin part number to order for the 15-piece cobalt drill bit set?
Order Irwin 316015. That is the manufacturer part number for the 15-piece cobalt alloy steel general-purpose drill bit set supplied in the Accessory Storage Case.
3) How does Irwin ship the 316015 set, and does that matter for a distributor buying for resale?
It ships 5 each per case. That master pack is retail-ready, so a distributor or wholesaler can break it straight onto a shelf, and an MRO buyer standardizing across several trucks or shops can take a full case and hand out one set per vehicle.
4) Does the Irwin 316015 case stack and lock with other Irwin accessory cases?
Yes. The redesigned Irwin Accessory Storage Case uses interlocking clips that connect case to case, so the 316015 stacks with other Irwin accessory cases to build one customized bit kit that travels as a block instead of loose boxes in a bag.
5) Can you tell which bits are missing from the Irwin 316015 case without opening it?
The lid is clear, so you can see the contents at a glance and spot a gap before you leave the shop. Bits are held in a patented pivoting bit-bar, which releases a bit easily and holds the rest in place so they do not spill when the case is carried sideways.
6) Where is the Irwin 316015 drill bit set made?
Country of origin is China. That is the detail government, education and healthcare procurement teams usually need up front for sourcing documentation on a purchase order.
7) Is the Irwin 316015 a single bit or a complete set?
It is a complete set, not an individual bit: 15 pieces of cobalt alloy steel general-purpose bits supplied in the storage case. If you only need one replacement diameter, buy an individual bit rather than this assortment.
