• Reduce costs
• Boost threading efficiency.

Landis standard and Coventry chasers are available in a variety of sizes, pitches and throat angles.

HSS Step Drill offered comes in titanium coated surface finish as well as can be made available in choice of multiple sizes like 6, 8, 10, 13mm and others. Further, the use of high speed steel metal for construction as well as availability in different grades also makes these deliver lasting service performance. Some of its features include CNC made construction for precision accuracy; size range of 3.0 to 60.0; available in choice of 5 steps to 16 steps; different surface finish choices like bright, tin-coating, cobalt coating and others; suitable for use on both alloyed and unalloyed steel.

Gun drills are straight fluted drills which allow cutting fluid (either compressed air or a suitable liquid) to be injected through the drill's hollow body to the cutting face. They are used for deep drilling—a depth-to-diameter ratio of 300:1 or more is possible. Gun barrelsare the obvious example; hence the name. Other uses include moldmaking, diemaking, and the manufacture of combustion engineparts such as crankcase, cylinder head, and woodwind musical instruments, such as uilleann pipes, as gun drills can drill long straight holes in metal, wood, and some plastics. The coolant provides lubrication and cooling to the cutting edges and removes the swarf or chips from the hole. Modern gun drills use carbide tips to prolong life and reduce total cost when compared with steel tips. Speed of drilling depends on the material being drilled, rotational speed, and the drill diameter; a high speed drill can cut a hole in P20 steel at 30 inches per minute.

Feature:

Reduce labor intensity of construction workers, speed up the construction speed, reduce construction costs for construction, installation, renovation, decoration industries.
The square chisel mortiser combines the cutting of a four-sided chisel with the action of a drill bit in the center, The bit clears out most of the material to be removed, and the chisel ensures the edges are straight and clean.
Hollow Mortising Chisel Bits are for making square mortises in one stroke and oblong mortises with each succeeding stroke.
