Different Paper Drill Bit Styles & Tips for Longevity

Standard Steel

A solid choice for everyday drilling on uncoated standard stock. Made in the U.S. to high quality standards.

CHT / Teflon

For thicker or tougher work. Best on laminated or coated stocks (matte, glossy, metallic). CHT (Chemicals, Heat, Time) adds a Teflon coating to reduce heat and prevent build-up inside the hollow bit, extending service life.

Fluted

Four internal flutes help break up slugs on harder stocks such as chipboard and card stock. Not recommended for softer stocks. The flutes tear the paper plug for cleaner evacuation.

Marvel

Titanium-coated for maximum durability—often ~4× longer life than standard steel. Ideal for thicker stocks and difficult jobs (plastics, heavy card). The hard outer coating maintains a sharp cutting edge while the softer core promotes a self-sharpening effect.

Tips to Extend Drill Bit Life

• Match the bit style to your stock and application.
• Set the drilling depth correctly—just through the bottom sheet. Smoke indicates the bit is set too deep.
• Sharpen during production as needed; intervals vary by stock (recycled and exotic stocks are harsher).
• Clean and lubricate bits to prevent clogging and overheating (CHT coatings help). Consider drill ease wax.
• Use the correct spindle setup and replace worn spindles to avoid over-penetration into wood blocks.
• Run the proper RPM for the bit diameter (see table).
