Compact bolt cutters CoBolt

The CoBolt compact bolt cutters group brings together 22 KNIPEX compact cutter codes for bolts, rivets, nails and metal wire. Models range from 160 mm to 250 mm, with recorded cutting diameters from Ø4.4 mm to Ø6.0 mm. Model 71 01 250 is made in Germany with a joint mechanism that increases hand force 40 times; model 71 12 200 states a factor of 35 times.

Induction-hardened blades reach approximately 64 HRC, chrome-vanadium steel, with straight, 20° angled and recessed blade versions. The suffixes SB, T and T BK reflect packaging and the attachment point for a fall-protection lanyard. The content below compares length, cutting diameter and head style for mechanics, electromechanical technicians and maintenance departments.

All codes are genuine KNIPEX, imported, with warranty.

The CoBolt compact bolt cutters group brings together 22 KNIPEX compact cutter codes for bolts, rivets, nails and metal wire. The product range spans lengths from 160 mm to 250 mm. Cutting capacity varies by model, recorded from Ø4.4 mm to Ø6.0 mm. The lever joint mechanism reduces the hand force required when cutting hard materials. Model 71 01 250 is made in Germany to KNIPEX Quality standards, with a joint mechanism that increases hand force up to 40 times.

Model 71 12 200 states a force increase factor of 35 times. Many models in the group use induction-hardened cutting edges reaching a hardness of approximately 64 HRC. The material is described as high-performance chrome-vanadium steel. The group includes straight blade, 20° angled blade and recessed blade versions. Some codes carry the suffix SB, T or T BK, reflecting packaging and the fitting of a fall-protection lanyard attachment point.

Weight varies from 200 g on the 160 mm model to 475 g on the CoBolt XL 250 mm model. In addition to the pliers, the page also lists a replacement barrel spring for the CoBolt 71 X2 200 cutter. This arrangement makes it quick to compare length, cutting diameter and head style. The 160 mm models are aimed at work in confined spaces. The 200 mm models serve everyday single-hand work. The 250 mm model handles large cross-sections and is operated with two hands.

General technical characteristics of the CoBolt line

The CoBolt line focuses on cutting round material with high tensile strength within a compact body. The description of the Knipex 71 line states a length of 200 mm and a weight under 400 g. This size allows it to be carried in a tool bag. Cutting targets include bolts, rivets, nails and various types of metal wire.

The cutting edges of many models are induction-hardened, reaching a hardness of approximately 64 HRC. Model 71 31 160 records this hardness level for its cutting edge. Model 71 21 200 uses high-performance chrome-vanadium steel and goes through several processing stages. This characteristic serves the cutting of hard round material such as bolts and steel wire.

The lever joint mechanism determines the cutting force obtained from the grip force. Model 71 01 200 cuts soft wire, hard wire and piano wire as well as bolts, nails and rivets up to Ø5.2 mm. Model 71 12 200 cuts hard steel wire of Ø5.2 mm, bolts and rivets of Ø6 mm, and includes an opening spring.

Classification by length and cutting capacity

Overall length determines both accessibility and maximum cutting cross-section. The group is divided into three main sizes: 160 mm, 200 mm and 250 mm. The 160 mm size suits limited spaces. The 200 mm size accounts for most of the codes on the page. The 250 mm size is intended for larger cross-sections. The recorded cutting diameter increases with length.

At the 160 mm size, model 71 01 160 weighs 200 g and cuts up to Ø4.4 mm, with a slim, compact cutting head. Model 71 31 160 has the same length but cuts up to Ø4.8 mm. At the 200 mm size, model 71 02 200 weighs 365 g and model 71 31 200 weighs 330 g, both cutting up to Ø5.2 mm.

At the 250 mm size, model 71 01 250 increases hand force up to 40 times thanks to its joint mechanism. Model 71 31 250 belongs to the CoBolt XL version, cuts up to Ø6.0 mm, weighs 475 g and is operated with two hands. These two codes are aimed at cutting tasks involving large cross-sections and materials of high hardness.

Cutting edge styles: straight, 20° angled and recessed

The head style directly affects the approach angle to the workpiece. A straight head suits head-on work. A 20° angled head assists flush cutting close to a surface. A recessed blade helps hold and handle thick material. Within the group, these three styles coexist at the 200 mm length, which is convenient when a different head style is needed while keeping the same size.

For angled heads, model 71 21 200 is angled at 20° for flush cutting close to a surface in limited spaces. Model 71 41 200 also uses a 20° angled blade and cuts up to Ø5.2 mm, handling protruding nails, screws and excess wire. Following the same design direction are 71 41 200 SB and 71 42 200.

For recessed blades, model 71 32 200 is 200 mm long, used single-handed, with an induction-hardened blade of approximately 64 HRC. Model 71 32 200 T cuts bolts, rivets, hard steel wire and piano wire up to Ø5.2 mm and can take a fall-protection lanyard. Two codes in the same group are 71 32 200 SB and 71 32 200 T BK.

Code suffixes and replacement parts

The suffixes SB, T and T BK added to the base code indicate packaging and equipment variants. The T suffix is linked to a hanging point or fall-protection lanyard. Model 71 02 200 T cuts bolts, rivets, nails and metal wire up to Ø5.2 mm and includes a safety hanging hook. The same style also includes 71 22 200 T and 71 22 200 T BK, both 200 mm long.

The SB variants include 71 12 200 SB and 71 32 200 SB, both 200 mm long. These codes serve mechanics, electromechanical technicians and industrial maintenance teams. Among the replacement parts is 71 19 200 01, a barrel spring for the CoBolt 71 X2 200 cutter.
