User questions & answers

Question:	What's up with the water connection? I read it needs to be replaced or something. I would need to be able to hook up a garden hose to this
Answer:	Check the features and details, dimensions shown there.
Question:	Where do we order parts for this drill
Answer:	I found the best way to assemble with the screws is use a drill with a 1/16 drill bite to make a pilot hole. The screws go in a lot easier. To answer the question yes the screws stay in.
Question:	I bought this with 3" and 4" core bits, but there is no pilot bit. Can you refer me to the appropriate pilot bit
Answer:	3-6 or so depending on kid

User questions & answers

Question:	I’m looking for the pilot bit, i have a sds max 1 1/4” x 7mm arbor with a 14” x 4” core bit what pilot bit attachment do i need
Answer:	No one offeres pilot bits because they would be too long and break. Make a plug out of wood to guide your core bit to get your hole started to prevent walking
Question:	Could you be more specific with an adapter for a 1/2" drill? Could you post a link to something that might work
Answer:	You need a core drill. They are rentable. You need a water connection as well
Question:	The threads are too far down in the drill to reach with a 1-1/4 7 adapter. What specific adapter works with this drill bit and a 1/2 inch drill
Answer:	You need a core drill to use this core bit.
Question:	Can this be used in a 3/8" drill and does it require an arbor? Don't know what 1-1/4 in -7mm shank means
Answer:	The 1 1/4" is the diameter of the spindle thread. The 7MM is obviously a typo. The 7 represents threads per inch.

Question:	Would it drill through rebar

Question:	Can I hook this up to a grinder witha 5/8" thread
Answer:	3 in OD
Question:	Will this fit in a cordless drill
Answer:	We drilled through a 8 inch cinder block wall with this bit. We also needed a 4 inch vent pipe...in our case for a dryer. It was difficult to get a standard 4 inch vent through the hole we bored. To have it work we inserted a sleeve through the wall made from sheet metal that was probably a little smaller than 4 inches and attached a 4 inch vent pipe on the inside and an outdoor vent on the other. This solution was easy and worked out great.
