Twist Drill Bits Non -Sparking
Secure Tools's Non-Sparking Twist Drill bits are used to drill holes in materials such as plastic, wood, and steel. However, they are most commonly used for metal cutting, and they are typically made of high-speed steel.
A Non-Sparking twist drill bit is a metal rod of a specific diameter that has two, three or four spiral flutes running most of its length. Two-flute drills are for primary drilling, whereas three- and four-flute drills are only for enlarging cast or punched holes in a production situation.
