Color Ring Torsion T-Type Tamper Bit is listed in a 25mm version. These Color Ring standard and torsion families extend the company's broader screwdriving-tool range, which also includes stainless and precision bits, sockets, ratchets and complete bit sets. KING HO CHANG CO., LTD. presents these products as part of its continuing manufacture of professional bits and bit sets and its design work on unique and patented screwdriving products. The company also identifies KHC Co., Ltd. as one of the leading manufacturers of screwdriving tools in Taiwan, placing the Color Ring families inside its professional-bit business. The Color Ring Bits II catalog groups six named profiles: Phillips, Pozidriv, Slotted, Hexagon, T-Type and T-Type Tamper. Among those standard Color Ring Bits II products, Phillips, Pozidriv and T-Type extend through 90mm, Slotted and Hexagon are listed through 75mm, and the T-Type Tamper page lists 25mm. The Color Ring Torsion Bits catalog mirrors the same drive-profile choices with Phillips, Pozidrive, Slotted, Hexagon, T-Type and T-Type Tamper variants. For the torsion family, Phillips, Pozidrive, Slotted, Hexagon and T-Type are each listed in 25/50/75/90mm, while the T-Type Tamper variant is listed at 25mm. A 25mm length appears across every named standard and torsion Color Ring profile in these product pages, giving the catalog a common short-format option across the listed drive types. The non-tamper torsion products all include 50mm and 75mm versions in addition to 25mm and 90mm, while the standard non-tamper pages also include 50mm and 75mm versions. The 90mm option is present on every listed non-tamper torsion profile and on the standard Phillips, Pozidriv and T-Type profiles, whereas the standard Slotted and Hexagon listings stop at 75mm. These pages therefore show both standard Color Ring and Color Ring Torsion lines across multiple drive profiles and lengths, complementing the company's high-torque ratchet screwdriver sets and broader bit-set manufacturing.
