I bought a diamond punching machine, which is usually used to punch air conditioning holes, range hood holes and so on. For others, but what bit size should I buy?

Household air conditioners generally use 50-80mm (in fact, 63mm is enough).

A 125mm drill is generally used for range hoods.

Home improvement punch to buy 50mm, Joker.

Exhaust fan-102 mm, water pipes generally use 50 mm, and other conditions are determined according to pipe diameter. Remember to buy telescopic poles.

Diamonds are commonly known as rhinestones or diamond drills for short.

Extended data:

Diamonds are commonly known as rhinestones or diamond drills for short.

Main uses of rhinestones

Household: holes with diameters of Ф1mm-Ф 25mm, such as air conditioning holes, water heater holes, yuba holes, range hood holes, exhaust fan holes, gas pipeline holes, upper and lower water holes, floor drain holes, toilet holes, heating holes, water pipe holes, line through-wall holes and chimney holes, can be directly drilled. According to the need, you can also drill holes in rows.

Project: concrete load-bearing wall opens a new door and a window.

Air conditioning, range hood, water heater and other types of reserved holes for drilling. Ventilation pipe opening, fire-fighting pipe drilling, slotting opening, wall demolition, floor demolition, blasting drilling, reinforcement drilling ... Ф1mm-Ф 25mm hole can be drilled directly. According to the need, you can also drill holes in rows. Can be directly drilled, as well as wall hole projects of various specifications and sizes.

The main characteristics of diamond are: accurate size and high construction precision; No vibration, noise and dust, meeting the requirements of environmental protection; No damage to the surrounding structure, no need to repair; The equipment is small in size, flexible in use and wide in application range;

Scope of application of rhinestones:

Drilling holes in underground protective fences and continuous walls; Floor, road, dam, tunnel, bridge and other reinforced concrete drilling;

Drilling holes on the cement surface of electrical appliances, telephones, air conditioners, gas, drainage, fire fighting and sanitary equipment;

Drilling and installation of all kinds of anchor bolts; Drilling holes on the cement surface of various large equipment; Adopt advanced diamond drilling machine and cutting equipment to quickly drill and open holes in concrete, stone and brick walls.
