Description
The 4-inch centerset faucet combined with an air switch represents one of the most practical and popular configurations for modern kitchen countertop installations. This professional DXF template provides countertop fabricators with exact hole patterns for this four-hole configuration, ensuring seamless integration of both the faucet fixture and garbage disposal air switch control. Centerset faucets feature compact spacing with all handles and spout mounting within a 4-inch spread, making them ideal for standard kitchen sinks and smaller prep sinks where space efficiency matters. The air switch addition eliminates the need for wall-mounted disposal switches, creating a cleaner installation that puts disposal control right at the sink deck. This template includes four precisely positioned holes: three for the centerset faucet assembly (spout and two handles) at standard 1.375-inch diameter, plus one air switch hole at 1.375-inch diameter positioned for ergonomic access. The 20-inch card width accommodates this complete assembly with adequate spacing between components to prevent installation conflicts and ensure proper clearance for below-deck hardware, plumbing connections, and the air switch pneumatic tubing.

Installation Overview
The centerset faucet plus air switch configuration requires precise hole placement to ensure both components function properly without interference. Center the three-hole centerset pattern over the sink centerline, positioning it 1.5 to 2 inches from the sink front edge for optimal spout reach and handle clearance. The three centerset holes should be spaced exactly 4 inches apart center-to-center, with the center hole for the spout and the two outer holes for hot and cold handles. Position the air switch hole approximately 3 inches from the nearest faucet hole, typically to the right side for right-handed users, though left-side placement works equally well. All four holes require 1.375-inch diameter drilling perpendicular to the countertop surface. The air switch requires a clear path beneath the deck for its pneumatic tubing to connect to the disposal power module, typically installed in the sink cabinet. When drilling in stone materials, use diamond core bits with continuous water cooling to prevent chipping and thermal stress cracks. For solid surface materials, carbide hole saws provide clean results. Always perform a dry-fit with actual hardware before installation, as some manufacturers may have slight variations in mounting hardware dimensions or spacing requirements.
CNC Cutting Notes
This DXF template integrates seamlessly with all major CNC programming platforms including Alphacam, EnRoute, RhinoCAM, VCarve, and Mastercam. The file contains four hole definitions organized on standard layers with precise coordinate positioning suitable for both CNC router and waterjet cutting operations. For CNC router fabrication with diamond tooling on stone materials, use a multi-pass drilling strategy: rough pass to 70 percent depth at higher feed rate, finish pass to full depth at reduced feed to minimize edge breakout. Recommended spindle speeds for granite and quartz range from 10,000 to 14,000 RPM with plunge rates of 15-25 inches per minute. The 1.375-inch hole diameter allows sufficient tool clearance while maintaining edge integrity. Waterjet cutting offers excellent results for this pattern, with the small hole diameter minimizing taper issues. For production efficiency, program all four holes in a single nested operation with optimized tool path sequencing to reduce air cutting time. The template coordinate system uses standard origin placement, making it simple to position within your larger countertop fabrication layout. Always verify hole positions with digital measuring tools after programming and before cutting, especially when working with high-value stone materials.
Material Compatibility
This centerset faucet and air switch template delivers reliable results across all common countertop materials with appropriate tooling selection. Natural stone materials including granite, marble, quartzite, and soapstone work exceptionally well with diamond core bits or CNC diamond routing tools. Maintain adequate coolant flow during stone drilling to prevent thermal cracking and achieve clean hole edges. Engineered quartz surfaces such as Caesarstone, Cambria, Silestone, and Hanstone require specialized diamond tooling rated for quartz fabrication. These materials are harder and more abrasive than natural stone, so expect faster tool wear and reduce feed rates by approximately 20 percent compared to granite. Solid surface materials including Corian, Staron, Hi-Macs, and Wilsonart Solid Surface accommodate this hole pattern easily with standard carbide hole saws or router bits. The homogeneous composition of solid surface eliminates concerns about subsurface voids or grain direction, making it highly forgiving. For laminate countertops, this pattern works but requires backing support during drilling to prevent delamination and bottom-side chipping. Consider using a sacrificial backer board clamped beneath the laminate during hole cutting. Concrete countertops require diamond core bits and patient drilling with light pressure to avoid aggregate dislodgment.
Where to Buy
Professional countertop fabricators have numerous sourcing options for centerset faucets and air switch components compatible with this template. Establish trade accounts with major plumbing wholesale distributors including Ferguson Enterprises, F.W. Webb Company, Hajoca Corporation, and Winsupply for access to professional pricing and technical support. Popular centerset faucet brands matching this 4-inch pattern include Delta Foundations and Classic series, Moen Banbury and Chateau collections, Kohler Coralais and Forte models, American Standard Chatfield and Colony lines, and Pfister Ashfield and Brantford designs. Each manufacturer offers multiple finish options from chrome and brushed nickel to oil-rubbed bronze and matte black. For air switch systems, InSinkErator offers the industry-standard SinkTop Air Switch with dual outlet capability, compatible with most garbage disposal brands. Alternative air switch suppliers include Waste King, Franke, and ISE with various button finish options to coordinate with faucet finishes. When specifying for client projects, recommend purchasing faucet and air switch from the same finish family to ensure color matching. Many faucet manufacturers now offer proprietary air switch buttons designed to coordinate with their faucet collections, providing the most cohesive aesthetic result.
