Bit set special 75 mm, 50-piece

The special bit set 75 mm from CIMCO, article 114606, gathers 50 bits for common and tamper-resistant screws. Each blade measures 75 mm. That length reaches screw heads seated deep inside mounting holes. Electricians and service technicians can work inside cramped enclosures. The 1/4 inch hexagon shank fits straight into cordless screwdriver chucks. Hand drivers with a 1/4 inch holder accept the same bits.

The range spans slotted, Phillips and Pozidriv profiles through to security systems. Pin Torx, pin hexagon, Tri-Wing, Torq-Set, Clutch and XZN bits are all present. Every piece is made of chrome vanadium steel. An impact-resistant plastic case of 195 x 135 x 38 mm keeps each bit in a fixed slot. The tray is clearly laid out with a slip-proof surface, so stocktaking before and after a shift stays quick.

What the special bit set 75 mm CIMCO 114606 contains

Construction and drive fitting

Every bit has a 75 mm body, close to twice the length of a standard insert bit. The 1/4 inch hexagon shank matches the chuck of a cordless screwdriver and the collet of a manual bit driver. Chrome vanadium steel gives the working tip its hardness. A universal bit holder with a permanent magnet is supplied with the set.

• 50 pieces, one bit per size
• Bit length 75 mm for deep mounting holes
• 1/4 inch hexagon shank to a common standard
• Chrome vanadium steel construction
• Universal bit holder, 1/4 inch, 60 mm long, permanent magnet
• Impact-resistant plastic case 195 x 135 x 38 mm with slip-proof tray

The 60 mm holder adds reach when a screw sits behind a panel wall or inside a machine recess. Its magnet keeps the bit from dropping while the tip is guided into place. The tray layout makes each size easy to identify. Returning a bit to its own pocket keeps the set complete between jobs.

Bit profiles in the set

Standard drive systems and security drives sit side by side in the same case. Slotted bits cover terminal screws, while Phillips and Pozidriv suit panel and appliance fasteners. The security section handles screws that resist ordinary drivers. Pin Torx and pin hexagon bits have a central bore for the anti-tamper post. Tri-Wing, Torq-Set, Clutch and XZN profiles complete the coverage.

• Slotted 4, 5, 6 mm and slotted with recess 4, 6, 8, 10 mm
• Phillips PH1, PH2 and Pozidriv PZ1, PZ2
• Square Robertson size 1 and size 2
• Hexagon socket 4, 5, 6 mm
• Hexagon socket with hole 2, 2.5, 3, 4, 5, 6 mm
• Torx T10 to T30 and pin Torx T8TR to T40TR
• Torq-Set TS6, TS8, TS10 and Tri-Wing TW1 to TW4
• Clutch C1, C2, C3 and XZN multi-tooth size 5, 6, 8

This spread lets one case answer most service calls without a second kit. Security screws on housings, meters and public equipment can be opened on site. Electrical, electronic and light mechanical work share the same shank standard. Sizes step in small increments, which helps match the tip to the recess and limit cam-out.

Common applications

Switchgear cabinets, control panels and distribution boards are typical workplaces for this set. The 75 mm length reaches terminal screws recessed behind rails and covers. Appliance and electronics repair benefits from the security profiles on sealed housings. Machine builders use the hexagon and Torx bits on countersunk bolts. Facility teams open metering equipment and enclosures fitted with pin Torx screws. The magnetic holder helps when a screw must be started overhead or at arm's length.

Catalog technical content

The catalog lists the set as a special bit assortment for all screw types, with emphasis on safety and special screws. The extra 75 mm length is stated for hard-to-reach positions where space is limited. Contents are given as one bit per size, plus a universal bit holder with 1/4 inch hexagon socket and permanent magnet, 60 mm long. Storage is an impact-resistant plastic box measuring 195 x 135 x 38 mm.

Storage and handling

The case closes flat and fits a service bag or a drawer in a workshop trolley. Each bit sits in a moulded pocket, which prevents tips from rubbing against one another in transit. The slip-proof tray surface holds the bits while the box is tilted. A quick visual check shows any missing size at the end of a shift.
