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.

Thanks to their square grinding, our machine thread drills are also suitable as hand-held tap drills. You have the choice between through-hole tap drills (blind hole drills) and basic drill tap drills. The through-hole tap is suitable for through holes where the chips can fall out. Taps for through holes have a longer cut but are more stable than basic hole drill. The ground hole drills are ground with a right-hand twist, which causes the chips to be ejected upwards, which is of course an advantage for ground holes. They have a very short cut to cut the thread as far as possible into the bore and to create a thread that is as long as possible. However, it should be noted that the stiffness of the taps is significantly lower in the case of the sizes M2 and M2.5. The taps are made of HSS steel and are suitable for threading in steel, brass, plastics, copper, cast steel, aluminum and stainless steel. If you always use sufficient cutting oil during the thread cutting, the service life of the taps is considerably increased. Particularly when cutting small threads in model construction such as M2, M2,5 or M3, we recommend our round winder. This allows a safe and accurate cutting of threads with a clearly reduced risk that the tapping tool breaks. If you want to drill a core hole but do not have a table book or a thread table, this is no problem. There is a simple rule of thumb for metric control threads. Just take the diameter of the tapping tap times 0.8. Example M5 = 5mm diameter x 0.8 = 4mm core hole drill.

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
