What kind of tool is woodworking square hole drill? How does it drill square hole truss wall connectors?

A woodworking machine tool for processing tenons (tenons) of wood products. The tenoner principle is that a square knife surrounds a drill bit and is used for drilling square holes and grooves. It must be noted that the mortise can not be used for milling, but can only be manually grooved.

To adjust the approximate depth of the hole, it should be noted that this adjustment can not accurately determine the depth of the hole and groove, but can only determine the approximate height of the bit.

Don't be greedy to cut to the end more often, try more often, but also conducive to the drill to discharge sawdust, that is, to keep the downward pressure lifting up the downward pressure lifting up.

The drill can not be used on the electric drill. The square drill bit should be used with the square drill machine (tenon machine). Square mortise and square hole drill is composed of middle core and outer sleeve. Clamping handle diameter: d = 19 mm. Professional wood drilling and square hole drilling are mainly used in woodworking.

The woodworking square hole drill lies in the existence of an impacting body. Using this working principle to drill steel, iron and materials requires high strength of the tool. The concrete principle is as follows: The square hole drill belongs to a kind of hardware tool, which is mainly composed of internal rotating impactor and external impactor. All kinds of existing drills can only process round holes, not square holes. To process square holes, it is necessary to use round hole drills or cutting machines to process rough holes, which are then manually chiseled.

While drilling the round hole with the inner rotating body, the material between the round hole and the square head wall is broken by the impact force transmitted from the electric hammer to the external impact body, and the square hole is processed once, and the dust can be discharged from the slag discharge pipe. By using square-hole drills of different specifications and choosing appropriate power square-hole drills, square-hole drills that meet the requirements can be drilled.
