Model: Part #25300 | Authorized Royal Distributor | Shipping: Free Shipping Included Precision Fingertip Control for Small Diameter Drilling Standard machine feeds are often too aggressive for delicate micro-drilling. The Royal 25300 provides the "feel" you need for bits as small as #80. By bypassing the heavy quill feed of your mill, this tool allows for manual, fingertip sensitivity that prevents bit breakage and protects expensive workpieces. Technical Specifications for Part #25300 Designed for high-accuracy environments, this unit features an isolated ball-bearing ring that ensures the operator feels the cutting resistance, not the machine's vibration.
