AI Technical Summary

Technical Problem

The existing method of using separate drill bits for pilot holes and screw driving is inconvenient, often leading to screw bending and wood breakage due to the hassle of bit replacement.

Method used

A drill bit design where the base is made thicker to accommodate the driver bit, allowing for direct transition from drilling a pilot hole to driving screws without the need for bit replacement.

Benefits of technology

This solution simplifies the process by eliminating the need for bit replacement, reducing the risk of screw bending and wood breakage, and ensuring more efficient screw driving.

Abstract

To solve the problem that, when a screw is driven in a wood material by an electric drill, exchange of bits is troublesome in a conventional manner, so that making a prepared hole by a boring bit is omitted and the screw is sometimes driven by a driver bit from the first time, and as a result, the screw is obliquely driven and the wood material is broken.SOLUTION: In this invention, to eliminate a troublesome exchanging work of a bit of an electric drill, a driver bit can be inserted into a boring bit as shown in figure 2. Thereby, after a prepared hole is bored by the boring bit, the driver bit can be used only by detaching the boring bit, and the exchanging work of the bit can be omitted.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a bit for an electric drill. Summary of the Invention [Problem to be solved by the invention]

[0002] Previously, when using an electric drill to drive a screw into wood, you would first drill a pilot hole with a drill bit, insert the screw there, and then drive the screw in with a driver bit. The reason for drilling these pilot holes is to ensure the screw is set straight and to prevent the wood from splitting. However, because it is a hassle to switch between the drill bit and the driver bit, people often skip the process of drilling pilot holes. From the beginning, I had to use a driver bit to drive in the screws. As a result, the screws would go in crookedly and the wood would split. [Means for solving the problem]

[0003] Therefore, the present invention is a method for eliminating this bit replacement work. As shown in Figure 2, the base of the drill bit was made thicker so that a driver bit could be inserted into it. In this way, after drilling a pilot hole with the drill bit, you can simply remove the drill bit and use the driver bit, eliminating the need to replace the bit. [Brief description of the drawings]
