Hand tools for assembly, installation and workshop use
This category brings together hand tools for lever work, hose fastening, height transfer, cutting and drain cleaning. The range includes pry bars and bolt clamps, hose water levels, replacement blades and hand-operated spirals. Construction, maintenance, plumbing and workshop tasks can therefore be matched to the right tool.
Selection by task
Hand tools differ less through general quality than through their purpose. A pry bar transfers force to nails, boards or components. A bolt clamp holds a hose of defined diameter on a pipe connection. A water level equalizes heights across distance, utility knife blades cut material to length, and a cleaning spiral reaches deposits inside a pipe. Knowing the working sequence therefore means choosing function and size first, and finish or weight afterward.
Levering and dismantling
For releasing tight connections, lever length, cross-section and point shape are decisive. A claw helps pull nails; a chisel edge helps chip material away.
Fastening hoses
Bolt clamps are selected by clamping range. Material, standard reference and hex fitting determine installation and area of use.
Measuring and leveling
Hose water levels use water as a shared height. Hose length determines the distance that can be handled without moving the setup.
Cutting and clearing
Snap-off blades with a known width fit compatible utility knives. Drain-cleaning spirals reach outlets over their length and are guided manually here.
Comparing pry bars
Two versions show the difference especially clearly. The longer model is described as 1200 mm long, with a bar cross-section of 2.8 x 1.5 cm and a reinforced handle made from hardened tool steel for resistance to abrasion and deformation. According to the product data, it suits pulling nails, chipping or breaking plates, and levering heavy objects.
The more compact 600-x-15-mm model is forged, hardened and painted in one piece. It has an upturned claw, a slightly angled chisel edge and a broad bearing surface. Its focus is controlled dismantling work with a shorter lever travel. Both variants have different weights, which can matter when working overhead or in confined positions.
The weights show the difference: the long model is listed at 3.68 kg and the shorter one at 5 kg. Extra mass in the shorter model can add force during striking or positioning, but makes holding it longer more tiring. On ladders, overhead or in narrow rooms, reach and controlled handling should therefore be considered in advance.
Sizing bolt clamps correctly
Bolt clamps, also called tension band clamps, always require the appropriate clamping range. It is specified in millimeters and must match the outside diameter of the hose on the connector. Clamps that are too small cannot close; clamps that are too large do not apply uniform contact pressure. The product cards range from 17–19 mm to 187–200 mm.
For material, the descriptions name galvanized W1 steel and W2 stainless steel. Several models refer to DIN 3017 and have a hexagonal fitting, which helps when choosing an installation tool. For suction and pressure hoses and applications in industry, agriculture or trades, standard, material and clamping range are therefore the main comparison axes.
A simple order helps selection: first measure the hose's outside diameter, then compare suitable clamping ranges, and only then distinguish between W1 and W2. The hexagonal fitting then shows whether a conventional hex wrench fits the installation. This distinguishes, for example, a small 21–23-mm clamp from a large 140–150-mm version even though both are constructed as bolt clamps.
Transferring heights with hose levels
A hose water level connects two points through a water-filled tube. The water surface marks the same height at both ends even when walls, foundations or garden areas interrupt the line of sight. The range includes a 15-m version and a 25-m model; the latter is described with funnels and a millimeter scale. The shorter tool is more practical for smaller components, while the longer one covers greater distances without moving the measuring point.
Weight also differs: the 15-m level is listed at 0.5 kg and the 25-m model at 0.7 kg. The difference is small, while the usable measuring radius increases considerably. On large sites this saves time because start point and target can be connected without frequent repositioning.
Blades, spirals and manual operation
The 10-piece set contains 18-mm snap-off blades for utility knives. They break off in segments, are made from high-quality steel and can be replaced individually. Blade width therefore remains consistent during replacement, and the knife keeps its guidance in the cutter head.
Drain-cleaning spirals are available in lengths of 5 m and 10 m, both hand-operated. The shorter spiral is listed at about 1 kg and the longer one at 3.1 kg. The latter is more flexible and can be inserted farther, but needs more space to guide. Choice depends on access to the drain, pipe run and desired effort.

Frequently asked questions about hand tools
Which pry bar suits dismantling work?
The 600-x-15-mm model is designed for shorter lever travel and direct control. It has an upturned claw and slightly angled chisel edge. At a greater distance from the workpiece or with higher force requirements, the 1200-mm version offers more lever length and is also stronger, at 2.8 x 1.5 cm.
How do you find the correct clamp diameter?
Measure the hose's outside diameter after it has been pushed onto the connector. The stated clamping range must include that value. One example from the range is the 64–67-mm clamp; other variants lie between 17–19 mm and 187–200 mm.
What is the difference between W1 and W2?
In product descriptions, W1 stands for galvanized steel and W2 for stainless steel. Several W2 clamps are described as corrosion-resistant. Many models also state DIN 3017, so standard reference and material can be compared separately.
Which hose water level is right?
The distance to be bridged is decisive. The 15-m version fits shorter measuring runs, while the 25-m model covers larger distances. The larger variant is specified with funnels having a millimeter scale and with a millimeter scale.
When should you use a 5-m or 10-m spiral?
The 5-m spiral weighs around 1 kg and is intended for more accessible drains. The 10-m version weighs 3.1 kg, can be inserted farther and needs more guidance. If the pipe route is unknown, it is sensible to begin at an accessible cleaning point.
Why are blade width and snap-off segments important?
The 18-mm replacement blades fit knives with the same blade width. They break off step by step, so a damaged segment can be removed while the blade remains guided in the knife.
In brief
This category organizes hand tools by concrete functions: levering, clamping, leveling, cutting and cleaning. For dismantling, length, cross-section and point shape matter. For hoses, clamping range together with material and standard is decisive. Hose length determines the working radius for height measurement, blade width matters for cutting, and reach matters for spirals. Separating these axes makes it quicker to find the right tool for the task.
