Problems Solved
- Poor dewatering or moisture handling in press applications
- Need for controlled drainage without through-drilling
- Surface pattern requirement for BDR press roll performance
Blind Drill Roll Manufacturer
Blind Drilling
Precision hole patterns for dewatering and press applications.
Service Overview
Blind Drilling
Blind drilling creates controlled hole patterns on roll surfaces to support dewatering, pressure distribution, and sheet handling in selected paper machine applications. Pattern selection considers roll position, covering type, hole size, depth, pitch, and operating duty.
Blind Drilling Service Scope
Blind Drilling creates controlled hole patterns on selected roll surfaces to support dewatering, pressure distribution, and press-section performance. Doghat plans Blind Drilling by reviewing hole diameter, depth, pitch, pattern, rubber covering thickness, hardness, and machine position.
Blind Drilling is not the same as ordinary drilling because the holes are engineered for surface behavior and do not pass fully through the roll. Doghat provides Blind Drilling for BDR press rolls, couch rolls, and other paper machine applications where drainage and moisture handling need controlled pattern design.

Frequently Asked Questions
Blind drilling creates holes that do not pass fully through the roll, helping selected rolls manage water and pressure distribution.
Yes. Hole depth, pitch, diameter, and pattern can be planned according to roll duty and covering suitability.
