Twist bits are most widely used drill bits which every repairer should have in their toolboxes. Featuring the recognizable, classic drill bit design, they can cut through a wide range of materials, from plastic and wood to concrete and steel. Twist bits are mainly available in fixed lengths, the most popular of which are Jobber drill bits featuring normal, standard lengths, which makes them suitable for a broad range of average job types. On our website, apart from these twist bits, we also offer many other high-grade bits in a number of length, shape, and material options.

The bits we offer are manufactured from heavy-duty, impact- and rust-resistant materials, to ensure the longest lifespan possible. Designed with a meticulous attention to detail, they provide clean, precise cuts. Twist bits can have 2, 3 or 4 spiral flutes running along most of their length. Two-flute drills are used for initial drilling, while bits with three and four flutes allow for enlarging punched or cast holes. Apart from twist bits themselves, we also carry a wide array of premium twist bit sets perfect for those who often perform repairs or realize DIY projects, or simply want to complement the existing toolset with a complete package of high-quality, durable bits.
