Draper Expert Impact Screwdriver Bit Set (26 Piece)

Build the ultimate impact driver accessory kit with the Draper Expert 26-Piece Impact Screwdriver Bit Set (IMBH26) — a professional-grade collection of screwdriver bits, nut drivers, and drive accessories engineered specifically for use with impact drivers and covering virtually every common fastener type encountered in automotive, construction, and general maintenance applications.

Purpose-Built for Impact Drivers

Standard screwdriver bits are not designed for the rotational shock loads generated by impact drivers. The IMBH26 addresses this directly — every bit in this set is manufactured from S2 steel, correctly hardened and tempered, making them impact-rated and far more resistant to the torsional stress, tip wear, and cam-out that quickly destroys standard hand-tool bits under impact use. A phosphate finish on every bit provides additional corrosion and oxidation protection for long-term service life.

Every Drive Type. Every Length.

This 26-piece set is structured across three working lengths — 25mm, 50mm, and 75mm — giving you the right reach for every application, from flush-surface fixing to deep-recessed fasteners. Combined with a magnetic bit holder and 1/4" hex to 1/4" square drive adaptor, the set provides complete flexibility across a wide range of impact driver and hand-tool scenarios.

The bit selection covers all major drive types encountered on the job:

Plain Slot — for traditional slotted fasteners across a range of widths.

Cross Slot (Pozidriv® compatible) — the most widely used fastener type in construction and joinery, covered across multiple sizes and lengths including triple coverage of the No.2 cross slot at 75mm for high-volume fixing tasks.

PZ Type (Pozidriv®/Supadriv® compatible) — purpose-designed for Pozidriv and Supadriv fixing systems, available in No.1, No.2, and No.3 at 50mm and with extended 75mm coverage on the high-demand No.2 size.

TX-STAR® (Torx® compatible) — T20 and T25 in both 25mm and 50mm lengths for the increasingly common Torx fastener systems found throughout automotive, appliance, and electronic applications.

Square Drive — S1, S2 (×2) and S3 across 25mm and 50mm lengths for Robertson-head fasteners widely used in construction and decking.

Magnetic Nut Drivers Included

Three magnetic nut drivers in 6mm, 8mm, and 10mm round out the set, providing direct hex nut driving capability without needing a separate socket and adaptor — ideal for sheet metal work, electrical enclosures, and automotive trim applications where quick nut fixing and removal is required.

Magnetic Bit Holder and Drive Adaptor

A 60mm magnetic bit holder keeps bits securely seated during use and makes bit changes fast and one-handed, while a 65mm 1/4" hex to 1/4" square drive adaptor allows the bits to be used with standard 1/4" square drive ratchets and T-handles — extending the versatility of the set well beyond the impact driver.

Supplied in a Plastic Case with Soft Grip Detail

The complete 26-piece set is presented in a plastic storage case with soft grip detail, with individual recesses for every bit and accessory. The soft grip case design makes it easier to handle and open with work-worn or gloved hands — a practical detail that makes a real difference on a busy job site or in a working workshop.
