## Summary description

Silver SDS Plus crown holder, model EX450, with a 450 mm length for use with SDS Plus rotary hammer drills. Designed to mount and secure core bits and crowns for drilling tasks in masonry and concrete. Provides a compatible connection to SDS Plus chucks and is intended for professional and DIY drilling applications requiring extended reach.

## Long description

Silver SDS Plus crown holder EX450 is a 450 mm long accessory designed to connect core bits and crowns to SDS Plus rotary hammer drills. It provides extended reach for drilling in masonry and concrete where standard-length holders are insufficient. The holder offers a direct SDS Plus connection and a robust shaft intended for heavier-duty drilling tasks that require stability and alignment over a longer working distance.
Advantages
The 450 mm length reduces the need for extensions or ladder repositioning by allowing deeper or hard-to-reach drilling from a single stance. Its SDS Plus compatibility ensures secure engagement with standard SDS Plus chucks and quick bit changes. The design emphasizes rigidity and alignment to reduce wobble when using core bits, contributing to more precise hole placement. The metal construction supports repeated professional use and higher load during continuous drilling.
Suitable for
 Drilling deep holes in concrete and masonry with core bits
 Jobs requiring extended reach, such as overhead or recessed drilling
 Professional and DIY applications where SDS Plus rotary hammers are used
Key specifications
 Shank type: SDS Plus compatible shank for direct rotary hammer connection
 Overall length: 450 mm for extended reach
 Material: metal construction for strength and durability
 Intended use: mounting and securing core bits and crowns for masonry and concrete drilling
How to use
Insert the SDS Plus shank of the crown holder into the drill’s SDS Plus chuck until it locks in place. Mount the core bit or crown onto the holder following the bit manufacturer’s mounting procedure and secure it properly. Operate the rotary hammer at appropriate speed and hammer settings for the diameter and material being drilled, keeping steady pressure and alignment to avoid side loads. Periodically inspect the holder and bit connection for wear or loosening during prolonged work.
Usage recommendations
Use appropriate personal protective equipment including eye and ear protection. Select a core bit rated for concrete or masonry and match the drilling parameters to the bit diameter. For extended or overhead drilling, ensure stable stance or use support equipment to maintain alignment and reduce operator fatigue.
