Description
An SDS (Slotted Drive System) drill bit size chart provides information about the standard sizes and dimensions of SDS drill bits commonly used in rotary hammer drills. SDS is a type of shank system that allows for quick and secure bit changes in these powerful tools. Here’s a general SDS drill bit size chart:
SDS-Plus (SDS+):
Diameter Range: 5 mm (3/16 inch) to 30 mm (1-3/16 inches)
Length Range: Typically 110 mm (4.33 inches) to 1000 mm (39.37 inches)
Shank Type: SDS-Plus, characterised by two open slots on the bit shank
SDS-Max:
Diameter Range: 12 mm (15/32 inch) to 52 mm (2-1/16 inches)
Length Range: Typically 200 mm (7.87 inches) to 1200 mm (47.24 inches)
Shank Type: SDS-Max, which has a larger shank than SDS-Plus for heavy-duty applications
SDS-Top (also known as SDS-Min):
Diameter Range: Smaller diameters, often below 5 mm (3/16 inch)
Length Range: Shorter lengths, typically used for precise drilling
Shank Type: SDS-Top, designed for small rotary hammer drills
SDS-Hex:
Diameter Range: Typically 6 mm (1/4 inch) to 13 mm (1/2 inch)
Length Range: Varies based on application
Shank Type: Hexagonal shank with an SDS-style head
It’s important to note that while these are common sizes, SDS drill bits can come in various lengths and styles to suit different applications, such as masonry, concrete, or wood drilling. The choice of SDS bit size depends on the specific job requirements, the type of material being drilled, and the size of holes needed.
