How to choose a drill to punch

Today the guns are widelyspread as a reliable tool for making holes in hard surfaces. To punch did not fail at the most inopportune moment you need to take care of high-quality components. Let's talk about how to choose the drill to punch.

Types of modern drills for punch

The most frequently used today, two drillssizes: SDS Max and SDS +. The first type of drills designed for heavy tools, and the first for drills and light middle class weighing up to 5 kg. The main difference between these drills is the maximum diameter and construction fasteners. For example, the Boers of sizes SDS Max have greater maximum length, diameter and weight.

In the market of construction tools you can findAdapters for drills, which allow the use of borax those sizes for which the guns are not designed. Although this possibility exists, however, experts strongly recommend its use as if punch designed to use size drills SDS +, the use of these components in a greater length, weight and diameter helps shorten the life of the tool.

Note the sludge removal rate

In today's market of construction materialsThree types are particularly prevalent Boer: screw, with a large and a small angle of inclination. Through use of the cutting auger principle possible to provide a high speed of disposal of sludge in those cases where a shallow thread groove. Therefore, drilling holes with large depth of auger drills will be the best solution, since they contribute to a small load on the tool and allow you to drill at high speed.

Choosing a drill to punch, it is important to consider that the product with a slight slopegrooves designed for prolonged operation with little effort. In using such drills should provide a minimum load. Of course, in this case, the expert hardly gets tired, but the penetration rate remains low. Such drills should be used to drill a large number of shallow holes.

In drills with a slight inclination of the grooves sludgeIt is given much more quickly, which improves work efficiency. However, with the increase in the speed of the punch load also increases. If you are aiming to increase the speed of drilling, use these drills. Just make sure that the tool does not overheat.

Choose manufacturer

Today you can find on the market a lotBoers manufacturers. In the low-price category, you can find the products of the Chinese and Russian producers. By the mid-market are "amateur" components of known manufacturers, if you are interested in a professional production of European companies, the need for them to shell out a considerable amount. Let's carefully examine the product for each price range.

The performance of Chinese and RussianBoers are pretty fickle. By their manufacture frequently hardening regime is disturbed, leading to premature failure of the product. Besides drills in this price range may be inaccurate dimensions of the connecting element, and the quality of products from the same pack can differ dramatically (one drill will last a long time, and the other may break almost immediately). The acquisition of these products is justified only when the hammer is used very rarely, and the desire to save almost uncontrollably.

Quite often such savings to no goodIt does not. Therefore, even for non-professional use is better to give preference to well-known brands Boers amateur category. These drills are not designed for constant and high loads, but in home conditions will be for many years to serve their masters, without causing them any problems.

After reviewing the sizes and types of drills, as well as considered the features of products from various manufacturers, we have identified key factors that will help in the right way choose a drill to punch.
