The T50 x 30mm Torx Star Bit 10mm (Draper Tools Group D, DR33355) is a dedicated screwdriver bit designed to drive T50 Torx (six-lobe) fasteners in confined spaces. Its primary use is to transfer torque from a driver or bit holder to Torx-head screws where repeatable, slip-resistant engagement is required, such as in mechanical assemblies, automotive panels and plant maintenance.

Manufactured from S2 tool steel and heat-treated for increased torsional strength and wear resistance, this bit has a 30mm working length and a T50 Torx profile at the tip. The drive end is a 10mm hex shank to suit 10mm bit holders, quick-change chucks and standard hex adaptors. The bit is finished with a corrosion-resistant black oxide/phosphate coating to reduce surface rust and aid longevity in workshop environments. The Torx profile conforms to the industry six-lobe dimensions used for Torx fasteners (equivalent to recognised ISO/DIN six-lobe internal drive specifications) so it mates accurately with standard T50 screws.

Typical applications include automotive repair and assembly, agricultural and earthmoving machinery maintenance, furniture and cabinet assembly that uses security Torx fasteners, and general engineering where higher torque transfer and reduced cam-out are required. The 30mm length gives enough reach for shallow recessed fasteners while keeping control in handheld or bench-mounted drivers.

Key benefits of this bit are its material strength and corrosion resistance: the S2 tool steel and heat treatment give the bit good resistance to twisting and premature failure, while the black oxide finish helps protect the surface from corrosion in workshop and outdoor conditions. The 10mm hex shank ensures compatibility with a wide range of bit holders and quick-change systems, allowing rapid interchange between drivers without losing bit retention.
