Working with brass requires specific techniques to achieve clean, precise holes. Many engineers face frustration with brass drilling – galling, walking drill bits, and poor surface finish can ruin projects and waste materials. What makes drilling brass different from other metals, and how can you get better results?<\/p>

The design of a drill bit affects how it cuts through brass. Here’s what to look for:<\/p>

<\/p>

The twist rate (helix angle) affects chip evacuation and cutting aggressiveness. A slower twist rate works better for brass – look for “slow spiral” or “low helix” bits. Standard bits have a 30\u00b0 helix angle, while bits designed for brass often use 15-20\u00b0 angles.<\/p>

<\/p>

While standard drill bits have a 118\u00b0 point angle, a slightly flatter 135\u00b0 point angle helps prevent grabbing in brass. This blunter point spreads cutting forces over a larger area, reducing the bit’s tendency to dig in suddenly.<\/p>
