20-count S2 steel Phillips insert bits

The Irwin Tools 357320 set supplies twenty #2 Phillips insert bits milled from high-grade S2 tool steel for precise fit in power-tool chucks. They are built for the higher torque demands of drill and quick-change adapters across appliance, automotive, aviation, decking, drywall, electronics, furniture assembly, general construction and HVACR tasks.

Shatter-resistant case with flip-top access

A large-capacity container moulded from shatter-resistant material stores all twenty bits securely. The ergonomic flip top opens with one hand and the wide-opening lid gives immediate access to the bit needed for the job.

Organised storage speeds bit changes

The case layout keeps every insert bit visible and separated, so the right driver is selected without rummaging. This reduces downtime on repetitive fastening work and protects the precision-milled tips from damage between uses.

Questions about this item

How do I load the 20 Irwin 357320 #2 Phillips bits into the case, and what step do people often miss?

Open the flip-top lid with one hand, drop each bit into its slot, then press the lid down until it clicks; the step most users skip is fully seating every bit so the shatter-resistant case closes flush.

What maintenance or replacement will the S2 tool steel bits need after extended use?

Inspect the #2 Phillips tips for rounding or chipping after heavy torque jobs; once the milled profile wears enough to cam out of fasteners, replace the individual bit — the case holds 20 so spares are on hand.

What limit appears first when driving screws continuously with these 1/4" hex shank bits?

The bit tip yields before the S2 steel body; sustained high-torque fastening rounds the #2 Phillips profile, causing cam-out and forcing a bit swap.
