HSS steel drill bit set

This twist drill set consists of 49 profile-ground drill bits. The twist drills have a particularly high concentricity and pitch accuracy, as well as a precise tip grind. You can recognize profile-ground drills by their bare surface. The drill set is delivered and stored in a practical metal box. Thanks to the precise tip grinding, the drills do not run and drill round, dimensionally accurate holes. The twist drill set is not a hardware store product but rather industrial quality. Thanks to the 0.1mm gradation of the drills, you always have the right drill at hand, regardless of whether you want to make threaded holes, an undersized hole for a reamer or an oversized hole for a shaft bushing with a clearance fit. Industrial quality (not hardware store goods) You have two different drill boxes to choose from: Twist drill set from 1mm - 5.9mm drill bits 49 pieces Twist drill set of 6mm - 10mm drill bits 40 pieces Replacement Twist drill to fill the drill boxes can be found here.  

Soft soldering paste for brass, copper, steel and silver steel. The paste is applied thinly to the parts to be tinned and heated with a brazing lamp. For large-area soft soldering, it is optimal to tin- the parts beforehand. For example, we use the paste to pre-tine the cylinder and the mirror when constructing a model steam engine. The tinning paste can also be used optimally as a flux substitute. The soft soldering paste is excellently suitable as corrosion protection for steel parts. Bengs Modellbau uses the zinc paste for steel cylinders with a cooling water jacket. For example in the Flammenfresser Kurfürst. Stirring the paste before use is not necessary! The soft soldering paste may be diluted with water.

Machine reamers for the production of dimensionally accurate bores. By rubbing with a reamer, not only good shape and dimensional accuracy, but also good surface quality is achieved. This is of crucial importance when manufacturing sliding bearings in mechanical engineering and model building. The long cutting edges of the reamer have a left-hand twist, which causes the resulting chips to be discharged downwards when rubbing. Thus, a scratching of the bore surface by the resulting chips is avoided. Our machine reamers have industrial quality and can be used to grind drillings in steel, brass, copper, cast iron, aluminum and stainless steel. Please always use enough cutting oil when rubbing, which considerably increases the service life of the reamer. In model construction, these reamers are suitable for producing piston rod guides for steam engines, Stirling engines and flame eaters. The reamers are also ideal for producing bearing blocks with plain bearings or for producing cylinders with a very clean surface. If you produce the axis bore with a reamer for flywheels, the flywheel runs particularly round. Provided you have the flywheel without impact in the lathe. The machine reamers can be used both on a lathing machine and in a column drilling machine.   With long cutting edges and link spiral Maximum roundness accuracy industrial quality   These reamers are available: Reamer 1H7 / Shaft 1mm / cutting length 16mm  Reamer 1,5H7 / Shaft 2mm / cutting length 21mm  Reamer 2H7 / Shaft 2mm / cutting length 26mm  Reamer 3H7 / Shaft 3mm / cutting length 29mm  Reamer 4H7 / Shaft 4mm / cutting length 46mm  Reamer 5H7 / Shaft 5mm / cutting length 57mm  Reamer 6H7 / Shaft 6mm / cutting length 56mm  Reamer 7H7 / Shaft 8mm / cutting length 71mm  Reamer 8H7 / Shaft 8mm / cutting length 80mm  Reamer 10H7 / Shaft 10mm / cutting length 91mm  Reamer 12H7 / Shaft 10mm / cutting length 110mm  Reamer 14H7 / Shaft 14mm / cutting length 112mm  Reamer 15H7 / Shaft 14mm / cutting length 114mm  Reamer 16H7 / Shaft 14mm / cutting length 123mm  Reamer 18H7 / Shaft 14mm / cutting length 135mm Reamer 20H7 / Shaft 16mm / cutting length 145mm  Reamer 25H7 / Shaft MK3 / cutting length 174mm  Reamer 26H7 / Shaft MK3 / cutting length 178mm 

For all machining processes that place high demands on a cutting and cooling lubricant. Particularly suitable for thread cutting, reaming, sawing, drilling, turning, scraping, punching and milling. Can be used for all types of steel, cast iron and stainless steel. Our cutting oil is also suitable for all non-ferrous metals, copper, brass, aluminum and their alloys. Using cutting oil significantly increases tool life. The cutting oil is chlorine-free and age-resistant. Content: 100ml
