Drill Bushings

Drill bushings are precision-engineered components used in jigs, fixtures, and machining setups to guide cutting tools like drills, reamers, and counterbores with exceptional accuracy and repeatability. By providing a hardened guide for cutting tools, drill bushings help maintain proper alignment, reduce tool deflection, and extend tool life, ensuring clean, consistent hole placement in high-volume and tight-tolerance applications.

Whether you’re working with dedicated production tooling or modular fixtures, Carr Lane Mfg.’s drill bushings deliver reliable performance, tight tolerances, and long-lasting durability. With a wide range of styles, materials, and mounting options available, we offer solutions to suit nearly any application or industry. Browse our full selection below to find the right drill bushing solution for your operation.

Technical Information

Drill Bushing Installation & Technical Data: Learn about installation procedures for Carr Lane Mfg. Drill Bushings.

Standard Drill Bushing Sizes: This chart contains all in-stock drill bushing sizes offered by Carr Lane Mfg. If your necessary drill bushing size is not listed on this chart, Carr Lane Mfg. can manufacture a custom part to meet your needs.

ANSI Standard Part Numbers: Carr Lane Mfg. drill bushing part numbers are listed in our pricing & availability tool utilizing ANSI standard part numbers. Use this guide to easily locate the part number you need.

Counterbore Data: Counterbores prevent binding and heat build-up due to excessive bearing length. This chart details ANSI counterbore depths to help you choose the correct Carr Lane .Mfg. Drill Bushing size.

Understanding Standard Drill Bushings: There are several different types of standard drill bushings available from Carr Lane Mfg.. Review our complete guide to bushing types from our Engineering Resources section.

What Are Drill Bushings Used For?

Drill bushings are a major element in modern manufacturing, serving as precision guiding elements in jigs, fixtures, and custom tooling setups. Their primary role is to locate, guide, and support drills, reamers, taps, counterbores, and similar shank-mounted cutting tools, ensuring holes are placed with consistent accuracy and proper alignment, even under high production demands.

In most jig applications, drill bushings act as fixed reference points that control the exact entry angle and position of the cutting tool. This minimizes tool drift, prevents misalignment, and helps reduce dimensional errors. By absorbing lateral forces and resisting tool deflection, drill bushings also extend tool life and improve hole quality, especially when working with hard materials or deep cuts. Whether in a mass production environment or a precision inspection station, drill bushings help ensure repeatability, speed, and quality, making them a cornerstone of efficient, high-accuracy manufacturing processes.

What Size Drill Bushing Do I Need?

With over 50,000 standard configurations of customary-sized bushings, finding the perfect fit for your operation can be daunting. Both customary and metric bushings are standardized by the American Society of Mechanical Engineers (ASME). In general, the length of a drill bushing should be approximately twice the diameter of the bush hole. This ensures a close diameter to the drill without dragging.

At Carr Lane Mfg., users can configure any size drill bushing and generate CAD drawings to ensure you receive the correct part designed to meet your needs. To determine the best size of bushing for your application and build your own custom drill bushing, explore our part configuration tool. You can also use our drill bushing hole size calculator to determine the proper installation hole size for standard press-fit bushings.

Types of Drill Bushings

Drill bushings are available in a wide range of styles, each tailored to specific fixture setups, production needs, and tool types. This family of products includes press-fit bushings, renewable bushings, liner bushings, and more. Each of these bushings serves different purposes, from being permanently installed to being utilized on long-lasting production runs.

Press-Fit Drill Bushings: Press-fit bushings are permanently pressed into a jig plate and are generally used in single-operation drilling or reaming. Once seated, they provide precise tool guidance, ideal for single-operation setups or jigs where the hole size and location will not change frequently. Their simple, durable design makes them a cost-effective choice for general-purpose drilling.
Renewable Drill Bushings: This type of drill bushing is designed to fit into liner bushings and can be easily replaced when worn or damaged without removing the liner from the jig. These are commonly used for large batch production and continuous use where frequent bushing replacement is expected. Renewable bushings are available in fixed or slip configurations, allowing either tight location control or adjustability for multiple operations within the same jig.
Liner Drill Bushings: Also known to some as a master bushing, liner drill bushings are permanently attached to a jig body to house renewable drill bushings. The liner acts as a guide and support for the replaceable bushing, allowing for quick swaps without compromising the jig body. They provide excellent wear protection and help extend the life of the fixture.
Castable Bushings: This bushing type is designed for cast-in-place or plotted installation and provides excellent holding strength against rotational forces, especially in applications where the bushing needs to resist torsional or rotational forces. These are ideal for non-metallic fixtures, such as those made from epoxy, urethane, or composite materials, and are commonly used in aerospace and low-volume prototyping environments.
Carbide Bushings: Appropriate for long-run, high-production drill applications, carbide bushings provide excellent wear resistance. Their extreme hardness ensures minimal dimensional change over time, even under constant use. Carbide bushings reduce tool wear, maintain hole precision, and are often used in automotive, aerospace, and medical manufacturing.
Chip-Break Bushings: Chip-break bushings are designed to break up chips from tough and stringy materials while reducing friction and heat buildup. This helps prevent tool clogging or surface scratching, which is especially useful when drilling into tough or gummy materials like aluminum, stainless steel, or brass.
Directed-Coolant Bushings: Featuring internal passages, directed-coolant bushings allow coolant to pass through the cutting area to wash away chips. DC bushings not only help flush away chips but also maintain cooler cutting temperatures, prolonging tool life and improving surface finish. They are ideal for deep-hole drilling and high-speed machining operations.
Oil-Groove Bushings: Like DC bushings, oil-groove bushings provide a coolant passageway but include grooves along the bushing’s ID wall. This internal lubrication helps reduce friction between the tool and bushing, preventing wear and galling, especially in high-cycle environments.
Gun-Drill Bushings: This type of bushing is used on a variety of gun drilling machines and is available in one- and two-piece constructions. Gun-drill bushings are designed to guide long, thin drills with high precision and are made to withstand the rigor of deep, high-speed drilling while maintaining tool alignment. They are commonly found in aerospace, mold-making, and firearm manufacturing.
Template Bushings: Template bushings are specifically designed for thin template jig plates and feature a retaining ring and serrated body to prevent spinning. These bushings allow for precise, repeatable drilling without shifting in the fixture, making them ideal for hand drilling or light machining applications in woodworking, electronics, and assembly jigs.
Threaded Template Bushings: Threaded template bushings are self-tightening bushings designed for thin template plates and can be easily removed to replace or reuse. They offer the same precision as standard template bushings but with added convenience and flexibility, especially in modular or changeover jigs where hole sizes or tool paths vary by part.
Circuit-Board Drill Bushings: These drill bushings are designed to accommodate the larger shank diameter of a circuit-board drill used in PCB fabrication. They provide precise tool guidance in ultra-fine, multi-layer drilling applications, ensuring accurate hole alignment across delicate or layered circuit boards.
Air-Feed Drill Bushings: This drill bushing type is designed for use with air-feed drills, tappers, and back spotfacers, all fitting with standard drill motors. These bushings guide the tool while accommodating the axial thrust and speed of pneumatic feed systems, ideal for automated or high-speed drilling setups.
