What industries use Silver & Deming drills?
They’re popular in construction, fabrication, maintenance, woodworking, and general metalworking.
What’s the best drill speed for large HSS bits?
Use slower speeds for larger diameters, especially in metals, to reduce heat buildup.
How do you sharpen a Silver & Deming drill bit?
They can be sharpened on a bench grinder or with a dedicated drill bit sharpener, keeping the correct cutting angles.
Do I need lubricant when drilling with HSS Silver & Deming bits?
Yes, in metals — cutting oil will extend the life of the bit and improve hole quality.
How do I choose the right Silver & Deming drill bit size?
Match the diameter to your required hole size and ensure your drill has the torque to handle the larger bit.
Do Silver & Deming bits have flat spots on the shank?
Yes — many have a 3-flat shank to prevent slipping in the chuck.
Are Silver & Deming bits only for drill presses?
No — they can be used in handheld drills, but due to their size, a drill press or magnetic drill is often preferred for accuracy and safety.
What’s the difference between HSS and cobalt Silver & Deming bits?
HSS is economical and suitable for softer materials; cobalt adds hardness and heat resistance for tough metals.
Can HSS Silver & Deming bits cut stainless steel?
They can, but cobalt versions are better for stainless and other hard metals due to increased heat resistance.
What materials can HSS Silver & Deming drills cut?
High Speed Steel versions work well in wood, plastics, and softer metals like aluminum, mild steel, and brass.
