Product Details
OKNIFE MBS1 4mm Double-Ended Bit Set
Compact, practical, and made for everyday carry
The OKNIFE MBS1 is a compact bit set designed for daily repairs, quick adjustments, and portable tool carry. It combines durable S2 tool steel bits, practical size options, and an extra Eternal Pencil in one easy-to-carry setup.
Premium S2 Tool Steel Construction
Built for strength and wear resistance
Durable material for repeated use
Each 4mm double-ended bit is made from premium S2 tool steel, a material known for strong hardness and good wear resistance. This helps the bits stay reliable during regular use and gives the set a solid, long-lasting feel.
Nickel-plated finish for added durability
The nickel-plated surface adds another layer of durability and helps support long-term performance. It also gives the bits a cleaner and more refined finish.
Versatile 9-Piece Bit Set
Multiple bit sizes for different tasks
One set, more everyday flexibility
The MBS1 includes 9 double-ended bits, giving you 18 usable tips in one compact set. It covers a practical range of sizes for repair work, adjustment tasks, and daily carry needs.
Included bit combinations
T1 + Triangle 2.3, PH00 + PH2, PH0 + SL3.5, SL1.5 + SL2, H2.5 + H3, H1.5 + H2, T10 + T15, T7 + T9, and T6 + T8.
Compatible 4mm Hex Bit Set
Designed for OKNIFE tools and other 4mm systems
Made for carry tools and compact drivers
This bit set is ideal for the Opry Series, D1 Series, and U1 Pro Series. It is also compatible with other 4mm hex nut drivers, making it a flexible option for users who already carry compact repair tools.
Eternal Pencil Included
More than a standard bit set
A reusable tool for writing and marking
Unlike a typical bit set, the MBS1 also includes an Eternal Pencil. It is reusable, does not need sharpening, and adds extra utility for quick notes, marking, or light writing tasks during work.
