Mortar rake for seeders SDS plus

	The SDS plus drill differs from a conventional drill in that it is more powerful and has a different chuck system.
	Thus, the types of drills that can be used in the SDS plus drill have different shanks than those used in conventional power drills.
	Electric drills and SDS type drills have different chucks, so the drill shanks are different.
SDS plus shanks
	The shank of the mortar rake designed for the SDS plus drill has the same type of female internal thread as the mortar rake designed for the angle grinder. It is screwed onto the male male thread of the SDS plus mortar rake adapter. However, the thread size is smaller than that of an angle grinder spindle.
	The mortar adapter designed for the SDS plus drill contains an external thread onto which the mortar is screwed, and at the other end has a shank designed to be inserted into the chuck of the SDS plus drill.
	Here the shank on the adapter is different.
	The adapter shank for SDS plus drills has four sets of flutes: two with an open end and two with a closed end. Two of these grooves are where the drill chuck ball bearings (closed end) rotate, and the other two are where the mortar rake shank (open end) enters. Therefore, the adapter is not firmly held in the chuck, as in a standard drill. Instead, the "open" and "closed" grooves along the shank of the mortar rake adapter form channels through which the ball bearings of the SDS and drill chuck can slide back and forth. This holds the up and down movement, preventing the nozzle from slipping or spinning freely.
	Unlike a standard planter, the SDS plus absorbs most of the vibrations during operation, making it easier to rake without negatively affecting the operator.
	The advantage of using the SDS plus drill is that the shank is inserted into the SDS drill chuck and twisted until it fits into the grooves in the chuck. The name SDS comes from the German "Sterk, Dreh, Sitz" (insert, twist, fasten), also known to Bosch manufacturers as the "Special Direct System".
	The SDS shank is called SDS plus shank or TE-C shank. These terms tell you what type of drill your chuck is designed for. "TE-C" is an alternative name established for drills and drills of the SDS plus type. The name "TE-C" is used by the global construction company Hilti.
	There are many types of SDS drills. SDS and SDS plus chucks and shanks are interchangeable. However, SDS Max accessories are not compatible with any of them.
	You can tell which adapter will fit your SDS plus drill because the shank diameter and the number and location of flutes along the drill shank follow the standard pattern for SDS plus drills.
	The mortar rake shown here is used with an adapter and is designed to fit on the SDS plus planter.
