10-Piece Interchangeable Blade Set
The WIHA 28194 set supplies ten individual blades that fit a single handle for Phillips, slotted and square fasteners. Tips measure 3.5 mm, 4.5 mm, 5.5 mm and 6.5 mm alongside #1 and #2 Phillips. Chrome vanadium steel blades store in a separate case and feature friction hold without magnetised tips.
Sustained Use Behaviour
Alloy steel shanks measuring 8 1/2 in resist twisting when torque is applied repeatedly across assembly tasks. Chrome vanadium construction maintains tip geometry through extended fastening cycles. Cushion grip reduces hand fatigue during long sessions while the non-magnetised tips prevent unwanted metal shavings from clinging to the blade.
Compatibility Check
Verify that your fastener heads match the supplied tip profiles and sizes before purchase. The 6 mm drive size must suit the handle or adapter you intend to use. Confirm that the separate storage case fits your toolbox layout. Note the California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.
