Description / Basics

A drill bushing is intended for precise centering, positioning and guidance of drills. They can be used in drilling rigs or for multi-spindle drilling heads as well as a drilling jig. Therefore, it is possible to create an accurate and recurring bore at the same position in one component. In addition, through the guide the drill bushing protects the drill from breakage. The most common bushings are the collar drill bushing according to DIN 172 and the cylindrical drill bushing according to DIN 179.

Drill bushings and collar drill bushings are available in a variety of fastening types. They can be pressed in or secured with a semi-circular notch in the collar of the plug-in fulcrum pins. Since it is not pressed, this has the advantage of quick interchangeability. MISUMI also offers the special form of a flanged bushing with mounting flange.
Collar bushings with oval bores are also available at MISUMI. These are provided with a semi-circular notch in the collar, which, in combination with a dowel pin, serves to align the collar drill bushing.

Drill bushings are often used as positioning bushings or centering bushings.
Due to the rounded insertion of the drill bushing, it can serve as a joining opening for centering pins or height adjusting pins.

Frequently Asked Questions (FAQ)

Question:

Can you press in a drill bushing?
Answer:

A drill bushing or collar bushing can be pressed in. However, it should be noted that the inner diameter of the drill bushing may become smaller if the tolerance is too tight. For more information, see the Technical Data Sheet available as a PDF. It is recommended to select a non-tight press fit and to additionally secure the bushing with screw locking agents such as Loctite.

Question:

Are there gentle positioning bushings for centring pins?
Answer:

MISUMI offers gentle drill bushings and collar bushings made of brass. These consist of a softer material than drill bushings made of steel. In the case of frequent joining processes, increased wear is thus directed onto the drill bushing and therefore the wear of the centring pin is reduced. However, wear should often be checked for brass bore bushings and attention should be paid to the resulting play.
Question:

What is a drill bushing?
Answer:

A drill bushing is primarily used to guide and centre drill bits. These are often used in drilling templates and drilling gauges and help to precisely enable a repetitive position of the drilling. In addition, a drill bushing of the guide and support of a drill helps and can protect it from breakage. The drill bushings are also often used as a positioning bushing for centring pins. This means that positioning bushings can also be used in a workpiece carrier.
Question:

Can a drill bushing corrode?
Answer:

A drill bushing made of steel can oxidize (rust). If necessary, a stainless steel drill bushing can also be used. MISUMI also offers the drill bushing and positioning bushing made of steel with various surface treatments. These are available in either burnished or nickel-plated and protect against corrosion.
Question:

How can you prevent tilting in a centring bushing?
Answer:

In order to prevent tilting, a positioning bushing with oval bore can be used, as this allows length compensation in one direction. A possible cause of tilting can be a misalignment caused by temperature-related expansion or stress. Alternatively, a sword pin with a conventional drill bushing can be used to prevent tilting.
Question:

Which fit for drill bushings?
Answer:

Which bore tolerance fits depends on the application and the selected external tolerance of the drill bushing. Often, an H7 tolerance for the bore is used for pressing in. For more information about fitting, see Dimensional Tolerances and Fits available as a PDF.
Question:

Does a drill bushing need to be pressed in?
Answer:

It is not mandatory to press in a drill bushing or positioning bushing. A socket drill bushing is assembled and disassembled with a shoulder screw. Another variant is the drill bushing with mounting flange (large collar with through-holes), which is screwed to the flange. MISUMI also provides cylindrical drill bushings and collar bushings with a lateral groove that can be fixed with an adjusting screw or set screw.
Question:

Do you have stainless steel drill bushings?
Answer:

The cylindrical bore bushings and collared bore bushings are available in steel, stainless steel and brass.
These can be selected to the usual dimensions such as DIN 172 and DIN 179. However, MISUMI also offers configurable drill bits the length of which can be individually adjusted to your needs in 0.1 mm increments and the diameter in 0.01 mm increments.
