Are all spline bits the same?
Spline bits have become much less common than SDS Plus or SDS Max. They are very similar in capacity and variety to the range available to SDS Max bits. The major difference is that chipping bits and drilling bits that are used for spline drive drills have different shanks as one is smooth and the other has splines.
Can I use an SDS drill bit in a hammer drill?
You should not use SDS drill bits in a standard drill. The chuck on a standard rotary or hammer drill is not designed for SDS drill bits. Standard bits can come loose, damage the drill and affect the quality of your work.

Make sure you have the right type of core bit. Once this happens, the core bit will need to be sharpened or stripped. The procedure involves removing a thin layer of the matrix in order to expose the diamonds so that the bit can start cutting again.
Can I use a normal drill for core drilling?
A core drill should always be used with a power drill, at minimum around 800 watts and at maximum somewhere around 1300 watts. Your chosen drill should also have a variable speed function (somewhere between 100 and 300 rpm) and it must also have a safety clutch!
What drill is best for core drilling?

Which is better carbide or diamond?
Superabrasive, diamond plated tools have a major edge over carbide—longevity and cut-rate set diamond tools apart from the rest. Initially, a diamond tool will cost more money, but this investment goes toward the extended life of the bit. Additionally, diamond tools have a closer cut tolerance than carbide does.
Will a core bit go through rebar?
Core drills cut easily through rebar, allowing the holes to be placed wherever it is most suitable. Holes of almost any diameter up to 60 inches are easily drilled to make openings for plumbing, electrical and HVAC installations.
