Alpha HEX525SS H5 x 25mm ThunderZone Hex Impact Insert Bit

The Alpha HEX525SS is a ThunderZone H5 hex impact insert bit, 25mm overall length with a 7.2mm body diameter and a patented spiral impact zone, supplied as a pack of 10 (manufacturer-stated).

Alpha states that ThunderZone impact driver bits have an engineered spiral torsion zone that distributes the applied impact evenly through the torsion zone, so cam-out is minimised under high impact and torque loads. The range also uses S2 raw material with full body hardness and a compression forged tip, and magnetism helps the bit grip the screw (manufacturer-stated).

The catalogue lists HEX525SS in the wrap column of its Hex Impact Insert Bit table with 10 pieces, which it describes as the pack for bulk storage, and also lists handi pack (10 pieces) and card (2 pieces) formats. It is an insert bit, so it goes in a 1/4" bit holder.
