CHTOOLS SPEED DRILL replaces imported twist drills in China

In the field of steel structure processing, the current profit is relatively low, so cost control is the key. At present, many companies in the market use imported internally cooled twist drills, but their prices are skyrocketing, the procurement cycle is so long that people are eager to wait, and they break from time to time, which seriously slows down the production progress, the cost is high, and the processing accuracy is also average. So how to solve these difficult problems?

The company introduced in this article mainly processes H-shaped steel and channel steel, and its export business also accounts for a considerable share. The materials processed are mainly Q235B, SS275JR, S235JR, etc., with a processing depth of 12-40mm.

The processing equipment is PEDDINGHAUS three-dimensional multi-axis drill, model BDL1250/9B, CNC system: Siemens, spindle interface: MT4, cooling method: MQL oil mist cooling.

The tools currently used by the company are imported internally cooled twist drills, which have relatively high procurement costs, put a certain amount of pressure on the company's capital flow, and have a long supply cycle. In addition, in the actual processing process, drill bit breakage often occurs, which not only increases the tool loss cost, but also disrupts the continuity of the production process, causing a lot of trouble for the overall production efficiency and product quality control.

Don’t worry, CHTOOLS taper shank spiral groove Speed drill (S10 - GMT4 - 2605 - B) is here to help!

Processing data

Taking the Φ22 specification as an example, compared with imported twist drills, the rotation speed is increased from 270r/min to 485r/min, the feed is increased from 87mm/min to 122mm/min, the time for a single hole is sharply reduced from 14 seconds to 10 seconds, the hole roughness reaches Ra6.3, and the hole diameter tolerance is controlled at +0.05mm. The most amazing thing is the number of holes drilled. Imported twist drills break frequently, but the new S drill is still in use with 400 holes. The customer approved it and asked us to stop the test.
