The decision to buy a reverse hammer is determined by the specialization of its application. Tool dimensions can play a significant role when access to the part is limited. For example, removing injectors from coked seats when repairing diesel car engines can be an impossible task without damaging the cylinder head. Here you need a small size of the tool, it is best suited with a pneumatic drive. The price of the fixture varies significantly depending on the method of implementation of the impact and the volume of tasks to be solved.
The reverse hammer is a tool that implements impact from the inside. This necessitates its use in order to press out bearings and bushings from their places. It is also indispensable for work on restoring the shape of the body.
Why you need a reverse hammer and how to choose one
The tool is designed to create a shock effect towards you. Such efforts in practice are most often in demand for the following types of work:
- straightening and extracting dents during body repair;
- pressing bearings out of seats in the crankcase and removing them from the axes of rotating units;
- extraction of valve stem seals;
- dismantling of diesel engine injectors stuck to the cylinder head.

The lack of highly specialized goals dictates the purchase of a universal set with nozzles for various applications. If you plan to carry out exclusively straightening work in a car service, it is advisable to purchase a reverse hammer in a set with nozzles designed for use with a spotter.
Types of reverse hammers
The metalwork tool for creating a retracting impact is of two types, depending on the method of driving the striker:
- manual;
- pneumatic.
The method of engagement of the reverse hammer end switch with the workpiece or workpiece, depending on the design, can be: as follows:
- vacuum;
- on glue;
- welded;
- mechanical.
Type of reverse hammer
To implement the connection, special nozzles are usually used. Their design is tailored to the task at hand and can be a mechanically adjustable assembly or a fixed shape metal tip to ensure a secure connection.
Vacuum
They are used in body repair for fixing on the paintwork in the process of restoring deformed areas, eliminating dents, concavities without damaging the paintwork, which is noted by the reviews. Adhesion is provided by creating a vacuum between the rubber suction cup on the hammer tip and the surface to be machined. For this, an ejector integrated into the handle is used, fed by compressed air from the compressor. The rarefaction arising under the nozzle initiates the work of atmospheric pressure, which presses the tool against the deformed surface. It turns out a kind of Velcro.
With glued suction cups
A strong connection with the body of the car can be provided by special glue applied to a removable suction cup that looks like a mushroom. After straightening, the binder is softened by heating and removed from the paintwork. Does not require subsequent painting.
Welded
Fixation with spot welding is used to straighten deep dents. In this case, partial or complete removal of the paintwork is indispensable. Tacking to the damaged surface is carried out using special devices for contact welding - spotters, powered by the mains.
Mechanical
This type of engagement is most often realized by using collets to facilitate the dismantling of bearings and injectors. For the latter, it is most convenient to use a reverse hammer with a pneumatic drive from an air hose. The mount can be designed to be used with the inner bore of the bushing when dismantled from the seat. Drives that attach to the outer rim of the bearing, or specially configured tooling for wheel hubs, are suitable for pulling off axle shafts.
Rating of the best reverse hammers
An overview of some models briefly describes their characteristics and scope. The range of tasks for which you need to buy a reverse hammer can only be narrowed down by its price. Specialized tools are more expensive, despite the limited application. But the quality of their production, as a rule, is higher.
