Automatic vs Manual Portable Drilling Machine – NITTO KOHKI

Magnetic Drilling Machine NITTO KOHKI Auto-Feed

Why Auto-Feed and Auto-Control machines are much better than Manual Drilling machines.

First let us have a look at the video here :-


1. AUTO FEED – NITTO make drilling machines Being AUTO FEED there is uniform pressure applied on the Broach Cutter during the operation which results in more life of broach cutters(MAXIMUM no. of holes). Because of uniform pressure the broach cutter does not over heat, which keep the teeth of the cutter safe from becoming blunt or get broken.
MANUAL – On the other hand when the Operator operates the machine manually (Manual Feed), non-uniform pressure is applied on the broach cutters, sometimes less pressure is applied and sometimes more because of this the cutter(of any Brand) gets heated and gets blunt more easily which results in lower life of Cutters.

2.AUTO FEED – There is load sensor in NITTO make Auto Feed Auto Control Machine,
because of this the machine will never take excess load, whenever there is excess load the machine will trip the motor. This reduces the chances of the cutters getting damaged to a great extent.
MANUAL – While in manual machine there are no such sensors and when non uniform manual pressure is applied, the cutters get damaged very easily, resulting in higher operation cost.

3.AUTO FEED – There is load sensor in NITTO make Auto Feed Auto Control Machine,
because of this in case of excess load the motor trips, this reduces the maintenance and protects the electrical components. This leads to very low breakdown and high productivity.
MANUAL – There is no such safety feature in these machines, and this results in higher maintenance and higher breakdowns. Thus decreasing the productivity and affecting smooth and continues production.

4.In NITTO make machines the cutting oil comes centrally from the arbor and automatically stops after the operation, thus no cutting oil is wasted.

5.SAFETY Features in NITTO machines:
If there is power failure, the machine stops operating and when the power comes back, it does not start automatically, thus avoiding injuries and hazards.

6. NITTO drilling machine can easily be used in a horizontal position to drilling holes in vertical beams.

These features are absent in other lower quality manual feed machines
The main cost of drilling is not that of the machine but of the broach cutters which needs to be procured regularly and this is where NITTO saves you a lot of money. Being an Automatic machine, NITTO- Japan make drill machine has load sensors which regulates the speed of drilling and the feed based on the load. In the case that the load increases too much then the machine trips off. This ensures that there is always uniform load on the cutter. So for a big company/project which has hundreds of holes to drill everyday, it makes a lot more sense to buy a better quality ( Japan make) automatic machine than purchasing an inferior quality product with regular breakdowns and high operational cost.
