DeWalt Screwdriver Bits — Best Sets & Impact Driver Compatibility
DeWalt screwdriver bits use the universal 1/4″ hex shank and fit any brand’s drill or impact driver. DeWalt’s own impact-rated ranges — Extreme Impact Torsion and FLEXTORQ — are engineered to handle the high torque output of DeWalt’s 20V MAX and FLEXVOLT impact drivers. This guide covers DeWalt’s bit ranges, the best sets for different needs, and which bits to pair with DeWalt impact drivers.
DeWalt Bit Ranges
| Range | Colour | Impact Rated? | Best For |
|---|---|---|---|
| Extreme Impact Torsion | Black | Yes — long torsion zone | Impact drivers, heavy construction, professional trade use |
| FLEXTORQ | Dark grey/black | Yes — FlexTorq zone | Impact drivers, available in longer lengths (50mm, 75mm) |
| Standard Screwdriving | Silver/chrome | No | Drill/drivers only, light-duty DIY |
Best DeWalt Bit Sets
DeWalt DT70543T Extreme Impact Torsion 34-Piece Set
DeWalt’s premium impact bit set. Every bit features CNC-machined tips for precision fit and a black phosphate coating for corrosion resistance. The torsion zone is one of the longest on the market, providing excellent shock absorption. Includes PZ1–PZ3, PH1–PH3, Torx T10–T40, hex bits, and a magnetic bit holder in a TSTAK-compatible tough case.
DeWalt DT71572 45-Piece Screwdriver Bit Set
A comprehensive general-purpose set at a competitive price. Covers PZ, PH, Torx, hex, and slotted bits in all common sizes. Includes both 25mm and 50mm bits, a magnetic bit holder, and a socket adapter. The bits in this set are standard grade (not impact-rated), making it better suited for drill/drivers than impact drivers. Excellent value for DIY users.
DeWalt DT70527 PZ2 Impact Torsion Bits (Pack of 25)
Bulk PZ2 bits for trade users who drive hundreds of Pozidriv screws daily. Each bit has the Extreme Impact torsion zone for maximum life in DeWalt (and other) impact drivers. Buying PZ2 bits in 25-packs is the most economical approach for high-volume screw driving.
DeWalt Bit Holders and Accessories
DeWalt’s magnetic bit holder (DT7701) features a sliding screw-lock sleeve and impact-rated construction. The TSTAK accessory cases are stackable and interlock with DeWalt’s TSTAK tool box system, making organisation easy if you’re already in the DeWalt ecosystem.
Extreme Impact Torsion vs FLEXTORQ: Which DeWalt Range?
DeWalt’s bit lineup can be confusing because they sell several ranges. Here’s the simple breakdown. The Extreme Impact Torsion range (black and yellow packaging) is their flagship impact-rated line. These bits have a torsion zone that flexes under the hammering action of an impact driver, preventing snapping. They’re the bits to buy if you use an impact driver for any serious work.
The FLEXTORQ range is similar but uses a slightly different flex zone design. In practice, both perform comparably. The Extreme Impact Torsion sets are more widely available in the UK and tend to be better value, so they’re what we’d recommend unless you find a specific FLEXTORQ set at a good price.
DeWalt’s standard (non-impact) bits are perfectly fine for drill/drivers and manual use, but should never go near an impact driver. They lack the torsion zone and will snap quickly under impact loads.
Which DeWalt Bits for UK Trades?
For UK tradespeople, the essential purchase is PZ2 impact bits — they cover the vast majority of screws used in UK construction. DeWalt’s DT70527 25-pack of PZ2 Extreme Impact Torsion bits is the go-to bulk buy. Pair that with the DT70543T 34-piece set (which adds PH, Torx, hex, and a magnetic holder) and you have comprehensive coverage for any job site.
For DIY and lighter work, the DT71572 45-piece set is excellent value. It’s not impact-rated, but includes a wider range of bit types and sizes at a lower price point — ideal for home workshops and general maintenance tasks.
