The Ultimate Guide to Self-Drilling Screws for Thick Steel
In the realm of construction and manufacturing, encountering a tough, thick piece of steel is not uncommon. These "mild steel" pieces are often complex, alloy-rich structures that present a formidable challenge for standard self-drilling tips. The key to overcoming this challenge lies in the use of top-tier self-drilling screws for thick steel.
Understanding the Challenge
Drilling into thick steel is not a walk in the park. One of the primary tasks a self-drilling screw must execute is the expulsion of excess material. While a hardened drilling point and sharp cutting blades assist with the initial drilling, it's the fluting that matters most. A screw with a sufficiently long and accurately designed flute facilitates the removal of the fine bits and shavings that accumulate during the spiraling action, avoiding drill burnout caused by the heat of trapped iron shavings.
The Market Deception
Many well-known brands claim their screws to be the ultimate self-drilling screws for thick steel or heavy-duty self-drilling metal screws. They advertise these as capable of drilling through steel above1/2" thick. However, the reality often falls short of the lofty claims made in marketing campaigns.
