शानदार यन्त्र
The media could not be loaded. शानदार । यह भेदन यन्त्र बहुत ही अच्छा है । हमने जैसा देखा और मंगवाया वैसा ही मिला हालाँकि इस भेदन यन्त्र को बगल से पकड़ने वाला हत्था साथ में नही मिला । यह यन्त्र बहुत ही अच्छे से काम करता है । इसकी मदद से हम बहुत आसानी से दीवार, लकड़ी, लोहा और ढलाई में छेद कर पाते है । सबसे अच्छी सुविधा कि इसमें हमे कोई भी बिजली का तार जोड़ना नही पड़ता है ।

Value for money tool
A very good value for money. Refinements in materials and precision moulding of parts used would further enhance rating. All the best

TOTALLY DIFFERENT TO DESCRIPTION
The item described in the ad is a cordless drill. What is pictured and what you get are 5 masonry drill bits. OK for the price, but the description is completely misleading.

It's a good hammer drill
The hammer drill serves it purpose well as drill through concrete But keyless chuck gets stuck due to force in drilling maybe Becomes difficult to remove drill after

37v printed on its battery. Actual battery voltage is just 20 volt when checked on multimeter.
Krost says and it is written on its battery that it is 37v but when I checked the batery when fully charged the batery is only 20 volt. Why there is so big difference of 17volt. Is Krost just fooling the customer's just to sell the product??

Seller kept wasting time by making false promises. Unprofessional and sell and disappear attitude.
Drill machine had no provision of holding drills! Instead of chuck it had a square socket. Then it's was seller's attitude, way of talking and zero support.
