Mixed Screwdriver Bits Sets
A mixed screwdriver bits set covers the head profiles you'll meet in a day's work — Phillips, slotted, Pozidriv, Torx, hex, and the security versions of each. They fit a 1/4 inch hex chuck, which is the standard on impact drivers, ratcheting screwdrivers, and most cordless drills. AIMS Industrial stocks bit sets sized for trade and industrial use, from 20-piece pocket kits to 200-piece master sets.
The bit profiles you'll find in a set
- Phillips — PH1, PH2, PH3, the standard cross-head
- Pozidriv — PZ1, PZ2, PZ3, common in European-spec equipment
- Slotted (flat) — multiple width and thickness combinations
- Torx — T8 to T40, standard in automotive and electronics
- Hex (Allen) — metric and imperial, in 1/4 inch hex shank format
- Square (Robertson) — common in decking and construction
- Security versions — Torx with pin (TR), tamper-proof Phillips, and security hex
Standard or impact-rated bits?
Impact-rated bits are torsion-zone engineered — the shank twists under load to absorb shock, instead of snapping at the head. If you're using an impact driver (and most tradespeople are), spec impact-rated bits and you'll spend less on replacements. Standard bits are fine in a manual screwdriver or a low-torque drill driver.
Brands stocked at AIMS
Wiha and Bahco are our preferred bit set brands for trade use — chosen because the tip geometry is accurate, the hardness is right (hard enough to last, soft enough not to chip), and the case closes properly when you throw it back in the toolbox. Stahlwille and GearWrench are stocked for premium and US-spec applications.
Choosing the right set size
A 20- to 30-piece set covers the everyday profiles for most trades. 50- to 80-piece sets add Torx, security, and metric hex coverage. 100-piece-plus sets are for workshops where one set serves multiple trades — automotive, electrical, and general maintenance.
Storage and case design
Bit set cases are not all created equal. A good case holds bits firmly enough to survive being dropped, makes it obvious when one's missing, and opens flat so you're not fishing through layers to find the right size. Look for cases with labelled bit positions, secure latches, and a slim profile that fits the toolbox or van drawer where the set will live. Empty slots will be obvious — refill them before they become permanent gaps.
Bit holders and extensions
A magnetic bit holder is a small accessory that earns its place in any kit — holds the bit clear of the chuck for tight access, and the magnet keeps fasteners on the tip when you're working at awkward angles. Long bit extensions (75mm, 150mm, 300mm) reach into recesses that would otherwise need to be disassembled. Both stocked alongside the sets.
