Adjustable Torque Driver Kits (BTK and BCK)
Borka Tool Kit (BTK) includes Borka Torque Driver (BTD) with 10-70 inch-lbs. range of adjustment. It is specifically designed for use indoors and outdoors as a compact and light weight torque tool kit, and is packaged into slightly modified cordura nylon pouch made by Maxpedition. BTK comes with a variety of 1" long chrome plated bits, 1/2" hex socket, 2" long extension, compact ratchet handle and optional accessories.
Borka Combo Kit (BCK) combines BTK with some Precision Torque Limiters (PTLs). These PTLs are not user adjustable and are preset to specific torque values outside the 10-70 inch-lbs. range of the fully adjustable Borka Torque Driver. PTLs, included into BCK configuration, are currently available only with 4 and 8 inch-lbs. presets.
BTK and BCK detailed information and instructions are provided by X-Ring videos.
More Info About the Borka® Torque Driver (BTD)
Our most innovative and advanced model of the Borka® Torque Driver (BTD), is Made in America by Pro-Shot, and provides a range of torque adjustment from 10 inch-lbs. to 70 inch-lbs., in 1 inch-lb. increments. This adjustment range is supported by two adjustment scales, one from 10 to 27 inch-lbs. and the other from 28 to 70 inch-lbs. Having two separate scales greatly improves resolution of the BTD adjustment, and makes it easy to set up torque driver with high level of accuracy and consistency. BTD is likely the smallest size torque driver with the largest size adjustment scale. It is designed to be operated with the right hand.
Compact and light weight (under 6 ounces), rugged, highly consistent and accurate torque driver has all metal construction. Torque driver components are made from stainless steel, hard anodized aluminum, and chrome or zinc plated alloy steel. This choice of BTD materials provides sufficient corrosion protection for use in the field. FYI, 1" long screwdriver bits, included into BTD kits, are made from S2 tool steel and hardened to HRc 58-60. Bits are chrome plated for a long term corrosion resistance.
BTD accuracy variation is less than +/- 4%, which is considerably better than usually accepted +/- 6% for the hand operated torque tools. In order to achieve this level of accuracy, BTD user is expected to follow instructions from video (see User Guides).
