[問題] wooden drill bit
最近得到一位客人的詢問 他要我們畫出drill bit 也提供圖檔給我們
我們按照他所需要的去redraw 但客人一直說不對 說圖沒有表現出shoulder or stepdown
我不清楚shoulder or stepdown是指什麼
google看到以下這段話 想說大家可能比較清楚我在問什麼
因為我對這領域完全不了解 所以想麻煩做木製家具的大大幫忙
可否告訴我到底drill bit的shoulder是指哪部份 謝謝
Red Head Multi-Set Depth Charge 3/8 Inch Diameter Drill Bit is used for RX
Drop-In anchors. The shoulder prevents over drilling, making it less likely
to hit reinforcing steel or post-tension cable in concrete. This drill bit
allows for no lost time or energy drilling farther than necessary, and since
the anchor is set at a specified depth, it does not drop too far into hole.
The drilling depth for this bit is 3/4 inch
