XEBEC Brush™ Crosshole Extra-Large
Newly developed bristle. Realized a longer tool life than other crosshole brushes with improved wear amount and manageability. Helps reducing the tool costs by separating the shaft and the brush so that only the brush needs to be replaced.
Applicable equipment
The tool can be mounted on an equipment which can control the rotation speed. The tool must be rotated over 8,000 min⁻¹.

Components
The brush and the shaft are separated. Only the brush needs to be replaced.
Special shaft
| Product code | Shaft diameter (mm) | Overall length (mm) | Applicable brush size |
| CH-SH-6 | φ6 | 150 | φ15 |
| CH-SH-8 | φ8 | 150 | φ20, φ25 |
Initial processing conditions
| Rotational speed | 7000 min⁻¹ |
| Feed | 300 mm/min |
| Number of paths | Forward rotation: 1 reciprocating motion, reverse rotation: 1 reciprocating motion |
The Brush will break off when:
○ machined beyond the maximum rotational speed
○ used with a pneumatic tool
○ rotated outside the cylinder (outside workpiece)
○ the distance from the hole entrance to the target is 20 mm or less
When attaching the tool on the equipment or the tool holder,
insert the shaft more than 30 mm and make sure it is attached firmly.
In the following cases when used under the initial processing conditions, the Brush may break off,
○ Off-center cross hole, angled cross hole and long hole
○ The diameter of the 2nd hole drilled is larger than φ12
