What is the difference between cobalt and titanium drill bits?
admin2025-08-09T18:09:16+00:00Cobalt bits are solid alloy and great for hard metals. Titanium bits are coated HSS—good for general use but coating can wear off.
Should you use lubricant when drilling metal?
admin2025-08-09T18:08:47+00:00Yes. Lubricants like cutting oil reduce heat and friction, extending bit life.
What speed should you drill metal at?
admin2025-08-09T18:08:19+00:00Slower speeds for harder metals, faster for softer metals. Keep it cool with lubricant.
How do you drill through metal without damaging the bit?
admin2025-08-09T18:07:47+00:00Use the correct bit, slow drilling speed, steady pressure, and cutting oil to reduce heat.
Do you need special drill bits for stainless steel?
admin2025-08-09T18:07:16+00:00Yes. Stainless steel is hard—use cobalt or carbide bits with slow speeds and proper lubrication.
Can you use wood drill bits on metal?
admin2025-08-09T18:06:47+00:00Not recommended. Wood bits dull quickly on metal and may break. Use bits specifically made for metal.
What are the best drill bits for drilling through steel?
admin2025-08-09T18:06:13+00:00Cobalt bits are best for hard steels, while HSS with titanium coating works well for mild steel.
What is a metal working drill bit?
admin2025-08-09T18:05:23+00:00A drill bit made from high-speed steel, cobalt, or carbide designed to cut through metal with the right speed, feed, and lubrication.
