How to Create Precision Bench Dog Holes: Tools and Guides for Your Workbench
Building a custom workbench requires precision, especially when installing dog holes for clamping and material support. Whether you are constructing an MFT-style table or retrofitting an existing surface, the accuracy of your hole spacing determines the utility of your workshop accessories. Achieving perfectly vertical holes is essential for ensuring that dogs and clamps seat properly without wobbling or losing grip. By utilizing specialized templates and drill locators, woodworkers can maintain consistent hole patterns across large surfaces. This guide explores the essential tools needed to create these holes, ranging from portable drill guides to comprehensive clamping sets that maximize your bench's versatility.
Selecting the right tool for your project depends on your specific size requirements, as benches typically utilize either 3/4-inch or 20mm standards. Investing in a dedicated drill guide or locator reduces the risk of angled or uneven holes that can compromise your workpiece stability. Once your holes are drilled, incorporating high-quality stainless steel dogs and clamping systems allows for secure horizontal and vertical material holding. Understanding the differences between these specialized jigs and hardware sets helps you build a reliable workstation that supports diverse woodworking tasks, from simple cutting to complex assembly, while ensuring long-term durability and consistent performance.

How to choose
Hole Diameter Compatibility
When creating bench dog holes, you must match your drill guide or locator to the specific size of your hardware. Options like the GOINGMAKE series offer dedicated templates for either 3/4-inch or 20mm holes. Using the correct diameter ensures that accessories like the HONGDUI 20mm bench dogs or the 3/4-inch bench dog clamp set fit securely without wobbling. Always verify whether your project requires the metric 20mm standard, common for MFT-style tables, or the imperial 3/4-inch standard to ensure all future bench top accessories remain compatible with your custom-drilled grid pattern.
Material and Tool Construction
The build quality of your drilling jig significantly impacts the longevity and precision of your workbench surface. The 20mm Drill Locator utilizes an aluminum alloy construction designed for use with electric drills. Opting for durable metallic materials provides a stable guide for your drill bit, which helps maintain vertical accuracy across multiple holes. When selecting a drill guide or template, consider that these tools are specifically engineered to assist in the construction of MFT tabletops, portable workstations, and cutting boards, providing a consistent framework for your woodworking setup.
Integrated Clamping Solutions
Beyond just drilling holes, consider how you intend to secure workpieces once the bench is functional. The Bench Dogs Clamp Set includes specialized components like silicone pads, ratchet wrenches, and vertical or horizontal clamping capabilities designed for 3/4-inch holes. Integrating these types of clamping tools into your workflow allows for more versatile holding power. By selecting a system that accommodates specific dog hole sizes, you ensure that your bench becomes a comprehensive workstation capable of managing various materials and project sizes efficiently and securely.
Accessibility and Extension
Certain bench dog designs offer functional advantages for working with thicker stock. The HONGDUI 20mm Bench Dog is manufactured from 304 stainless steel and features an extension capacity of 40mm above the table surface. These dogs are designed for 20mm chamfered holes and include expansion locking O-rings to keep them firmly in place. When planning your bench dog system, assess whether you require standard flush-mount dogs or extended-height options that allow for better leverage and support when planing or sanding thicker woodworking projects on your MFT-style workbench.
Template Versatility
Templates serve as the foundation for an organized grid, which is essential for repetitive tasks on a workbench. The GOINGMAKE portable drill guides are designed specifically for creating uniform dog hole patterns across large surfaces like workbench tops or cutting boards. By using a dedicated drill template, you ensure consistent spacing, which is critical for using accessories like bench dog clamps effectively. Whether you are building a new MFT-style table from scratch or upgrading an existing workbench, utilizing a structured guide helps achieve professional-grade alignment across your entire workspace.
Frequently asked questions
Should I choose 20mm or 3/4-inch bench dog holes?
The choice depends on the existing accessories you intend to use. The 20mm size is commonly associated with MFT-style tables and high-precision stainless steel dogs like the HONGDUI models. Conversely, 3/4-inch holes are standard for many North American clamping systems, such as the Bench Dogs Clamp Set. Before drilling, check the requirements of your bench dogs and clamps to ensure a perfect fit, as these diameters are not interchangeable.
What tools are needed to drill accurate dog holes?
To achieve professional results, you should use a dedicated drill guide or locator jig, such as the aluminum alloy 20mm Drill Locator or the GOINGMAKE portable drill templates. These tools provide the necessary stability for your electric drill to maintain a vertical orientation. Using a template ensures that your holes are perfectly spaced and perpendicular to the bench surface, which is vital for the functionality of your bench dog clamps and accessories.
Can I use bench dogs on a standard wooden workbench?
Yes, you can upgrade a standard wooden workbench by adding dog holes. Tools like the GOINGMAKE portable drill guides are specifically designed for building MFT-style table tops, allowing you to create a grid on your existing workbench surface. Once the holes are drilled to the correct 20mm or 3/4-inch specification, you can utilize various bench dogs and clamping sets to increase the utility of your workspace for cutting and assembly.
Do I need a chamfer reamer for my dog holes?
A chamfer reamer is a beneficial tool for finishing the edges of your dog holes. The 20mm Drill Locator is designed to function as a bench dog hole chamfer reamer tool. Chamfering the edges prevents the wood from splintering and makes it significantly easier to insert bench dogs and clamping hardware into the holes without catching on the sharp edges of the workbench material.
How do I ensure my bench dogs stay in the holes?
Stability can be improved by selecting bench dogs with expansion features. For example, the HONGDUI 20mm Bench Dogs utilize an expansion locking O-ring design to ensure they remain secure within 20mm chamfered holes during use. Always verify that the dog you choose is compatible with the diameter of the hole you have drilled to ensure the O-ring or expansion mechanism functions correctly for reliable holding power.
Bottom line
For woodworkers building a high-precision MFT-style table, the combination of the GOINGMAKE 20mm portable drill guide and the HONGDUI 304 stainless steel bench dogs represents the strongest, most cohesive setup. The GOINGMAKE guide provides the necessary template accuracy for consistent hole placement, while the HONGDUI dogs offer superior durability and an expansion locking O-ring system for secure clamping. If your workflow requires heavy-duty holding power, supplementing this with the 3/4-inch Bench Dogs Clamp Set—provided you match the hole diameter—adds versatile horizontal and vertical clamping options. This ecosystem ensures that your workbench is not only accurate during the drilling phase but also highly functional for a wide variety of professional woodworking tasks.
Deciding between these tools requires evaluating your existing hardware ecosystem. If you already own accessories sized for 3/4-inch holes, prioritize the GOINGMAKE 3/4-inch drill guide and the comprehensive Bench Dogs Clamp Set. If you are building a new, modern MFT-style workbench, the 20mm standard is the optimal choice, supported by the 20mm Drill Locator and the HONGDUI stainless steel dogs. Always prioritize a drill guide that matches your specific dog diameter to ensure a precise, wobble-free fit. By matching your drill template to your planned clamping hardware, you create a robust, modular workstation that minimizes setup time and maximizes your accuracy across every project.
