选择最佳钻头的购物考虑

钻头类型

• BRAD-POINT钻头：This fluted drill bit is designed for use on wood. It features a sharp spur on the tip and spiral grooves (flutes) on the sides. The sharp tip helps position the bit in the right spot, and the flutes are designed to grab wood chips and expel them from the hole as you drill, resulting in a clean hole. Brad-point bits make speedy work of jobs that require a high degree of detail.
• 扭曲钻头：该标准位具有尖尖的切割尖端，与BRAD-POINT比特相同，特征在钻孔时将废物除去废物。扭曲位是家用的通用钻头，可用于木材，薄金属和塑料。
• Countersink钻头：Considered a specialty bit, the countersink bit is designed to创造一个试验洞顶部有更宽的开口，用于孤立螺钉头。主要用于木材，柜台钻头允许您将紧固件置于足够深处，使得头部不会突出材料表面上方。
• 福尔斯特纳钻头：For use on wood, the Forstner bit, named after its 19th-century inventor, Benjamin Forstner, features the same tip spur as a brad-point bit for precise drilling, but the body of the bit is designed to drill a flat-bottomed hole. Forstner bits are used to create holes to hold dowels (not screws) and are often found in high-end furniture and cabinetry construction.
• 铲子钻头：Also called a paddle bit, a spade bit comes with a tip spur for precision and a flat blade that’s designed to cut large holes—up to 1.5 inches across. Spade bits are commonly used to drill holes through wood studs to run wires and water-supply lines.
• 孔锯钻头：Used for making large holes in wood, thin plastic, ceramic tile, and other sheet goods, hole saw bits usually come in two pieces: the bit itself—a cylinder with sharp, saw-like teeth—and a mandrel (shaft) that attaches to the bit and fits into the drill.
• 步进钻头：该金字塔形钻头主要用于扩大现有孔，并且与薄材料 - 通常是金属板 - 但也可以在片材塑料上使用。制造商通常在钻头上的钻头上标记每个“步骤”，它钻头。步进钻头也可以通过加宽足够的孔的顶部来替代埋头钻头来凹陷紧固件头部。

Size Specs

In the United States, standard drill bits are most often sized in fractional, 1/64th inch increments, commonly ranging from 1/16th inch up to one inch. If you need a larger hole, you can opt for a spade bit or hole saw bit. Bit size may also be labeled in millimeters and decimals, but don’t worry about trying to figure out which sizes are equivalent—conversion charts are posted everywhere bits are sold, and they can be found online as well.

材料问题

虽然所有钻头由金属制成，但某些类型的金属比其他类型的金属更好，用于钻孔在不同类型的材料中的钻孔。

• Carbon steel bitsare designed for drilling in wood; they shouldn’t be used to drill through metal because they tend to heat up too quickly and may break.
• 高速钢（HSS）钻头are made by combining alloy metals with tungsten or molybdenum to create a bit that withstands high temperatures better than carbon steel bits. HHS bits are suitable for use on wood, soft metals, and fiberglass.
• Titanium HHS bits具有薄的钛涂层，可减少摩擦力，并帮助提示保持更加锐利。钛涂层的HHS可用于木材，玻璃纤维，硬质塑料和软金属，如铅和铝。
• 黑色氧化物HHS位采用薄薄的氧化物涂层，有助于降低生锈和腐蚀，使其成为潮湿或潮湿条件的良好选择。它们适用于大多数表面，包括木材，薄金属（如铜片）和玻璃纤维。
• 钴钻头are manufactured by combining steel alloy with cobalt to form a super-strong drill bit. Cobalt bits are designed for drilling through metals, including aluminum and stainless steel.
• 碳化钨钻头比HHS位更难，几乎完全用于通过陶瓷瓷砖钻孔和masonry,虽然部分的脆性使他们更多的prone to breaking.
