Do these go into a standard drill?

Dear valued customer Greeting! The diamond drill bits are compatible with most drills Warmest regards, StarQualityBargain Team

Why are these called "diamond hole saws" if they are made of corundum? corundum is not diamond.

Thank you for inquiry. The glass hole saw was coated diamond on the head for superior cutting strength. The description has been revised, thank you for your kindly reminding.

What sizes really are in this product ? The "Product Description" says '"0.63", 0.11", 0.79" ', but the title says ' (1/4"-2") '

Dear valued customer Greeting! The diamond drill bits 15 sizes : 0.24", 0.32", 0.4", 0.48", 0.55",0.63", 0.11", 0.79", 0.87", 0.98", 1.02",1.11", 1.18", 1.57", 1.97" . So the title shows 1/4"-2" Warmest regards, StarQualityBargain Team

Will this cut 1/2" safety glass?

Dear valued customer Greeting! Yes, the diamond hole saw can cut 1/2" safety glass. Warmest regards StarQualityBargain Team
