Phillips Power Bits — Quick Reference
Phillips power bits are the 1/4 inch hex-shank cross-head bits that drive Phillips screws from a cordless drill, impact driver, or bit-holding screwdriver. AIMS stocks PH00 through PH4 across six brands, in standard and impact-rated (torsion) grades, from 25mm carded singles to 400mm extension bits.
| What you need | Look for |
|---|---|
| Everyday driving, drill or driver | PH2, 25mm, standard grade — the highest-volume size and length in the range |
| Cordless impact driver use | Impact-rated / torsion-zone bits — look for "Thundermax", "Maxdrive Torsion", "Supatorq" or "Torsion Zone" in the title |
| Small screws, electronics, appliance work | PH0 or PH00 (Wiha stocks both) |
| Larger structural fasteners | PH3 or PH4 |
| Deep recess, panel or fixed-hardware access | 75mm–150mm extended bits; Alpha stocks a 200mm and a 400mm option |
| Double-ended or mixed-drive convenience | Double-ended bits pairing PH2 with slotted, Pozidriv or square drive on the other end |
| High-volume production work | Bulk packs — 10, 20, 25 or 100-packs, depending on the line |
| 1/4" hex tool alternative | Two lines (one Alpha, one Wiha) are made for 5/16" hex chucks — check the variant before ordering |
Brands in this range: Alpha, Sutton Tools, Bordo, Wiha, Hobson and Ko-Ken. Related ranges: Torx power bits, screwdriver bits, Phillips screwdrivers, bit holders.
Phillips Power Bits at AIMS
A Phillips power bit is the cross-head insert bit that fits a 1/4 inch hex drive — the tool that drives Phillips screws when a cordless drill or impact driver is doing the work instead of a hand screwdriver. AIMS carries close to 90 individual Phillips power bit products across six brands, covering the full PH00–PH4 size range, standard and impact-rated grades, and lengths from short 25mm carded bits through to 400mm extensions.
Phillips sizes stocked — PH00 to PH4
- PH00 — the smallest size we stock (Wiha only), for fine fastener and appliance work
- PH0 — small Phillips screws, electronics and light assembly
- PH1 — smaller general-purpose screws
- PH2 — the everyday size — the majority of Phillips power bit products in this range are PH2, and it's the size worth keeping in bulk
- PH3 — larger Phillips fasteners and structural screws
- PH4 — the largest size stocked, for the largest Phillips heads
A couple of brands mark sizing their own way on the pack — Bordo uses "PH #1–#4" and Ko-Ken's older-style bits are labelled "No. 1" to "No. 4" — but they correspond directly to the same PH1–PH4 sizing.
Shank fitment — 1/4" hex, with two 5/16" exceptions
Almost every bit in this range is a standard 1/4 inch hex shank, fitting any standard drill chuck, impact driver, or bit holder. Two products break that pattern: an Alpha Phillips impact bit and a Wiha Phillips insert bit are both made with a 5/16 inch hex shank instead, for tools set up around that larger drive. Check the shank size on the product page before ordering if you're not running a standard 1/4" holder.
Standard versus impact-rated (torsion) bits
This is the decision that matters most for bit life. A standard bit is solid hardened steel end to end — fine for hand driving and light drill work, but it has nowhere to give when an impact driver's hammering action loads it up, so it snaps or the tip rounds out fast. An impact-rated bit builds a torsion zone into the shank that flexes slightly under each impact and absorbs the shock, instead of passing all of it straight to the tip. In this range that's what Alpha's Thundermax and Maxdrive Torsion lines, Sutton's Supatorq and impact-rated CRV bits, and Wiha's "Torsion Zone" bits are built for. If the job is impact driver work — which most trade screw-driving now is — spec an impact-rated bit and you'll get through far fewer of them.
Bit length — what's actually stocked
- 25mm — the standard short bit, and the most common length across the range
- 45mm–65mm — a step up for slightly deeper recessed screws
- 75mm–100mm — extended reach for panel-mounted hardware and deeper fixings
- 110mm–200mm — long-reach bits for specialist deep-access work
- 400mm — the longest option stocked, an Alpha PH2 double-ended driver bit for the deepest access jobs
Brands stocked at AIMS
Alpha is the deepest Phillips power bit range we carry — insert bits, double-ended bits, and the Thundermax and Maxdrive Torsion impact-rated lines, in carded, handipack and bulk-pack formats.
Sutton Tools covers Phillips power bits through the S1xx and S2xx series, including the Supatorq impact range and Ultrabit line, sold as singles, carded and multi-piece sets.
Wiha is our premium Phillips power bit line — the only brand we stock down to PH00, plus the Torsion Zone, Xeno and Dura Tip variants for extended bit life.
Bordo covers Phillips insert and double-ended power bits in clam and carded packaging, including the Grippa range.
Hobson stocks Phillips drive bits in S2 alloy steel, including black-finish and titanium nitride coated options under the Impax name, plus bulk 25-packs.
Ko-Ken rounds out the range with 1/4" drive Phillips screwdriver bits, including the No.1–No.4 sizing used on their older product lines.
Sets, bulk packs and singles
Phillips power bits here are sold as single carded bits, handipacks of 2–4, and bulk packs — commonly 5, 10, 20, 25 or 100 per pack depending on the line — plus multi-piece sets covering a spread of PH1–PH3 sizes in one box. If you're fitting out for production work, buying PH2 in a bulk pack is the straightforward way to stop a job stalling because the bit box has run dry.

Frequently Asked Questions
What size Phillips power bit do I need?
It comes down to the screw, not the tool. PH1 suits smaller general-purpose screws, PH2 covers the majority of standard wood and sheet metal screws and is the size to keep spares of, and PH3/PH4 step up for larger structural fasteners. Wiha's range also runs down to PH0 and PH00 for fine work. If you're unsure, check the screw manufacturer's spec sheet or give us a call.
What's the difference between a standard bit and an impact-rated bit?
A standard bit is solid hardened steel and is built for hand driving or light drill use. An impact-rated (torsion) bit has a flexible zone built into the shank that absorbs the hammering action of an impact driver instead of transmitting it straight to the tip, so it lasts far longer under that kind of load. If you're driving with an impact driver, use impact-rated bits.
Do all these bits fit a standard drill or impact driver?
Almost all of them — the range is predominantly 1/4 inch hex shank, the universal fitting for drill chucks, impact drivers and bit holders. Two products (one Alpha, one Wiha) are made with a 5/16 inch hex shank for tools set up around that size, so check the shank size on the product page if that's relevant to you.
What lengths are available?
From 25mm carded bits right through to a 400mm extension bit, with common steps at 45mm, 65mm, 75mm, 100mm and 150mm in between. Shorter bits suit everyday driving; longer bits are for recessed screws or where you need extra reach to the fastener.
Can I buy these in bulk?
Yes — most lines are available in bulk packs of 10, 20, 25 or even 100, on top of the single carded and handipack options, which is the more economical way to buy for production or fitout work.
Do you also stock Torx power bits?
Yes, in a separate Torx Power Bits collection, plus the wider screwdriver bits range covering other drive types.
